If you want every meaningful secret in Just Cause 3, prioritize Ancient Tombs, Rebel Shrines, Di Ravello tapes, the Mile High Club, and Medici’s remote easter-egg islands. The tombs and shrines provide real progression rewards, while the scattered wrecks, strange buildings, and hidden references deliver the game’s most memorable discoveries. This route explains what each location gives you, how to reach it, and which secrets are worth your time.
Before hunting anything, unlock the three main islands through the story and liberate settlements around your target. A liberated province reveals more map information and removes most hostile patrol pressure, which makes a huge difference when you’re trying to search a cliffside with a helicopter instead of fighting a military convoy every thirty seconds. Keep the Rebel Drop menu stocked with a helicopter, a fast car, and the Bavarium Splitter assault rifle whenever possible.
The game’s official Steam page for Just Cause 3 remains useful for checking the base game and its downloadable expansions. This guide focuses mainly on the original Medici map, but it also points out where the Air, Land and Sea Expansion content changes the treasure hunt.
Ancient Tombs hide the best practical rewards
Ancient Tombs are the first secret locations you should clear. They aren’t merely scenic ruins: every completed tomb unlocks a new Rebel Drop vehicle. The entrance is usually marked by a stone structure, a narrow opening, or a vertical shaft that is easy to miss when you’re flying across the countryside. Use the grappling hook to pull open movable stone doors, then follow the blue-lit interior route.
The tomb puzzles are built around Rico’s tether. Look for counterweights, breakable wooden braces, and stone blocks that can be dragged into pressure positions. You don’t need a special weapon, but the CS Spectre submachine gun is handy for destroying fragile supports without wasting rockets. If the path appears blocked, check above you: several tombs expect you to grapple to a ceiling ledge rather than solve the room from ground level.
There are 23 Ancient Tombs in Medici. Each one contributes to the tomb collection and grants a vehicle unlock, making them far more valuable than ordinary sightseeing. The reward is delivered through the Rebel Drop system, so complete the tomb, open the menu, and look for the newly available vehicle rather than expecting a physical crate to appear beside the exit.
| Secret type | Collection count | Reward | Best search method |
|---|---|---|---|
| Ancient Tombs | 23 | One Rebel Drop vehicle per tomb | Search ruins and stone structures after liberation |
| Rebel Shrines | 49 | Rebel Drop support progression | Check villages, churchyards, and hilltops |
| Di Ravello tapes | 71 | Audio lore and completion progress | Use the map and sweep military compounds |
| Vintage parts | Several sets | Classic vehicle unlocks | Follow wreckage and isolated roads |
How to search tombs without wasting time
Start with a helicopter and land on the highest nearby point. Tomb entrances often sit below the road, not beside it. If you spot a circular stone pattern or a ruined arch on the map, drop a waypoint and circle the site once before jumping out. After entering, avoid blowing up every object: explosives can move puzzle pieces into awkward corners and turn a thirty-second tether solution into a frustrating reset.
The most efficient loadout is a grappling hook with multiple tethers, a precision rifle for distant switches, and a parachute with enough stamina upgrades to recover from bad jumps. You can also use the wingsuit to leave quickly, but don’t launch until the reward notification has appeared. If the game fails to register the completion, exit the tomb, return to the entrance, and check the collection tracker rather than immediately repeating the entire puzzle.

Rebel Shrines are smaller and less dramatic than tombs, but they’re essential if you want to complete Medici’s collectible progress. There are 49 shrines scattered through settlements, cemeteries, coastal villages, and elevated religious sites. Most are stone altars with a red or white rebel marker. They can blend into the scenery, especially in towns where balconies, church walls, and market stalls create visual clutter.
Approach a shrine and interact with it to record the discovery. You don’t have to destroy it, and there’s no combat puzzle attached. The real trick is reaching the location safely. Several shrines sit inside hostile provinces, so liberating the nearby settlement first makes the interaction much less annoying. If soldiers interrupt the activation, grapple to the roof, clear the immediate patrol, and return rather than triggering a full alert.
Di Ravello tapes work differently. These 71 audio collectibles are normally found around military installations, government buildings, palaces, and urban compounds. They’re small enough to disappear against concrete, so use the map marker and listen for the collectible prompt while sweeping balconies and interior rooms. The tapes reward completion and story context, not a new weapon, but they’re among the best secrets for players interested in Medici’s political history.
| Collectible | Where it appears | What you receive | Completion advice |
|---|---|---|---|
| Rebel Shrine | Villages, ruins, cemeteries, hilltops | Rebel support progression | Activate it after clearing the local alert |
| Di Ravello tape | Military and government compounds | Audio lore and collection progress | Search buildings, roofs, and courtyards |
| Rebel drop icon | Unlocked after relevant activities | Weapons, vehicles, and supplies | Check the drop menu after each milestone |
The easiest sweep pattern
Don’t hunt tapes randomly across all three islands. Pick one province, liberate it, and clear every marked collectible before moving on. The map becomes much easier to read when you combine the in-game filter with a low-altitude helicopter pass. Land near the center of a compound, collect the tape, then use the wingsuit to reach the next marker. This avoids the slow cycle of stealing a car, hitting a roadblock, and climbing another tower.
For shrine hunting, search the edges of settlements first. The game frequently places them outside the obvious central plaza, beside a cemetery wall or on a small rise behind houses. The best open-world shooters on Steamoz may offer more conventional loot systems, but Just Cause 3’s collectibles are deliberately about movement and discovery rather than inventory management.
Vintage parts unlock classic cars across Medici
Vintage parts are among the easiest secrets to overlook because they don’t behave like ordinary collectibles. Each set is spread across a small search area, with individual parts sitting near wrecked vehicles, dirt roads, garages, docks, or abandoned structures. Collect the complete set and you unlock a classic vehicle through the Rebel Drop system. These cars are not the fastest machines in the game, but they’re excellent rewards for players who want unusual handling and a break from military hardware.
Search slowly. A helicopter makes the initial approach easy, but landing directly on a part can obscure the pickup prompt with the rotor wash and vehicle wreckage. Touch down twenty or thirty metres away, then use the map marker on foot. Parts often have a distinctive metallic silhouette and are positioned beside a rusted body shell. If you see a wreck but no prompt, circle the area: the part may be on the opposite side of the road or behind a low wall.
These rewards are also useful for garage testing. Classic vehicles tend to have weaker acceleration and protection than modern rebel cars, so they’re poor choices for a Panau-style chase through a military base. They shine on scenic roads, stunt jumps, and challenge routes where precise steering matters more than armour. Save one in a garage after unlocking it, then call it through Rebel Drop whenever you want a clean run without enemy reinforcements.
| Reward category | Strength | Weakness | Best use |
|---|---|---|---|
| Vintage cars | Distinct handling and style | Low armour and modest acceleration | Road trips, stunts, and collection completion |
| Rebel vehicles | Flexible and easy to request | Usually less durable than military vehicles | Fast travel and liberated settlements |
| Military vehicles | Firepower and durability | High alert risk and slower handling | Convoy ambushes and base assaults |
Why these rewards matter late in the game
Once you’ve unlocked enough upgrades, vehicle variety becomes the point. The best car for a collectible route isn’t necessarily the fastest one; it’s the car that can survive a bad landing and still get you back to a garage. Pair a vintage vehicle with the Repair Vehicle gear mod and avoid unnecessary collisions. If you’re chasing challenge scores, compare handling rather than top speed because a controllable car will beat a faster one on narrow mountain roads.
For a broader look at games built around aggressive movement and improvised combat, Steamoz’s games like Hunt: Showdown feature is a useful change of pace. Just Cause 3 is far less tactical, but its vehicle secrets reward the same willingness to leave the obvious route.
The Mile High Club and Medici’s biggest easter eggs
The Mile High Club is the headline easter egg. It’s a ruined floating nightclub located offshore, and it’s easy to mistake the surrounding debris for an ordinary destroyed structure. Reach it with a helicopter or wingsuit, then explore the platforms and interior wreckage. The club doesn’t grant a new weapon or a permanent stat boost, but it’s packed with environmental details and stands as one of the clearest callbacks to the series’ earlier chaos.
Because the location sits over open water, bring a parachute and avoid landing directly on unstable wreckage. The grappling hook is safer than trying to jump between broken platforms. If you fall, swim away from the debris before redeploying a parachute; Rico can get trapped beneath the structure when the camera clips against the wreckage. The safest route is to land on the broad upper deck, inspect the central room, and work outward.
Medici also contains unusual monuments, isolated ruins, oversized statues, and small developer jokes hidden away from mission routes. Some are visible only from the air, while others are tucked behind cliffs or on tiny islands with no obvious reason to visit. Don’t expect every secret to produce a reward. In Just Cause 3, the reward is often the discovery itself: a strange vista, a reference to another game, or a perfect launch point for a wingsuit run.
The official Just Cause website is worth checking for series background, while Avalanche Studios’ game information provides the developer-side context. These sources won’t replace an interactive collectible map, but they help separate genuine game content from fan-made rumors about nonexistent super weapons.
Secrets that are fun but not worth grinding
Several remote curiosities are excellent screenshots and terrible completion targets. If a location has no collection icon, no interaction prompt, and no Rebel Drop notification, treat it as an easter egg rather than a missing reward. Players often waste hours searching the sea for an imagined unlock because a video thumbnail promises a “secret weapon.” In the base game, genuine rewards reliably connect to activities, collections, or the Rebel Drop menu.
Hidden rewards from DLC and challenge progression
Some of Just Cause 3’s most useful hidden rewards come from activities rather than map collectibles. Liberating settlements, completing story missions, finishing faction activities, and clearing challenges expand your Rebel Drop inventory and unlock gear mods. The Bavarium Sea Heist, Land Mech Assault, and Sky Fortress expansions also add their own equipment and locations, so a 100-percent base-map sweep is not the same as completing every secret in the full edition.
The most important upgrade path is the gear-mod system. Gear Mods improve practical tools such as the grappling hook, parachute, wingsuit, explosives, and weapon handling. Don’t spend every token as soon as you get it. For secret hunting, prioritize grappling-hook range and tether capacity, parachute control, wingsuit manoeuvrability, and explosive reserves. These upgrades directly reduce traversal time and make tomb puzzles more forgiving.
| Progression target | Reward type | Priority | Why it helps secret hunting |
|---|---|---|---|
| Ancient Tomb completion | Rebel Drop vehicles | High | Provides transport variety and collection progress |
| Gear Mods | Traversal and combat upgrades | Very high | Makes cliffs, tombs, and remote islands easier to reach |
| Challenges | Gear Mod tokens | High | Improves wingsuit, parachute, weapons, and explosives |
| Story and faction missions | Weapons and Rebel Drops | Medium | Expands the toolkit used for difficult compounds |
| DLC activities | Special gear and vehicles | Optional | Adds separate secrets beyond the base Medici map |
A practical 100-percent route
First, complete enough story missions to unlock all major regions and basic Rebel Drops. Second, liberate provinces so map markers and safe travel become available. Third, clear Ancient Tombs and nearby Rebel Shrines in the same circuit. Fourth, sweep military areas for Di Ravello tapes and finish vintage-part searches while you’re already in the province. Leave remote easter eggs for last, when your wingsuit and parachute are upgraded.
Use fast travel whenever the game offers it, but don’t rely on it for every trip. Several secrets become obvious only when you approach from the air and notice an isolated platform, ruin, or shipwreck. A good rhythm is helicopter to waypoint, wingsuit across the gap, grapple through the final approach, then Rebel Drop back to a liberated settlement. It’s faster than road travel and much less likely to turn a collectible run into an accidental ten-minute firefight.
If performance gets rough during large explosions, lower screen-space reflections, shadows, and water quality before dropping texture quality. Just Cause 3’s destruction systems can hammer CPU performance during military alerts, while textures generally have a smaller effect on frame rate. Steamoz’s PC stutter troubleshooting guide has broader optimization advice, and the official Steam community hub is useful for checking platform-specific bugs.
Finally, remember the distinction between a secret and a collectible. Ancient Tombs, Rebel Shrines, tapes, and vintage parts have trackable rewards. The Mile High Club and remote islands are exploratory discoveries. Chase both, but don’t judge the second group by the first group’s reward structure. Just Cause 3 is at its best when the map gives you a reason to leave the road, fire the grappling hook into nowhere, and see what’s waiting on the other side of the mountain.
