The best hidden secrets in Age of Empires on PC are not usually invisible treasure rooms. They are tucked into randomised relic spawns, campaign triggers, unused-looking terrain, developer jokes, and cheat-code units such as the Cobra Car and Furious the Monkey Boy. Most of the discoveries below apply to Age of Empires II: Definitive Edition, the version most PC players mean today, while a separate section explains what changes in the original Age of Empires and its Definitive Edition.
That distinction matters. Age of Empires is not an open-world game with a fixed list of caves to visit. In skirmish, the map seed changes resource placement, terrain, relic positions, and sometimes the safest route to the enemy. A “secret location” is often a patch of terrain you would never inspect during a normal build order. In campaigns, meanwhile, hidden discoveries are more likely to be tied to a named trigger, a neutral unit, or a scripted objective.
Relic Spawns Are the First Places to Search
Relics are the most important hidden objects in a standard Age of Empires II match, and they are easy to underestimate. Each relic sits on the map as a small golden religious artifact. A monk can pick it up and carry it to your Monastery; once deposited, it generates 0.5 gold per second, or 30 gold per minute, for as long as you keep control of it.
The location is not fixed in ordinary random-map play. The game places relics in neutral territory, usually away from starting Town Centers, with the exact pattern controlled by the map script and seed. That means experienced players do not memorise coordinates. They read the terrain. Relics commonly appear near open neutral ground, behind awkward forest edges, beside hills, or in pockets that are dangerous to reach without military cover.
Use your first Scout Cavalry to identify likely relic corridors rather than wandering aimlessly. On Arabia, check the spaces between the two bases and the back corners behind each starting woodline. On Arena, look beyond the walls and around the central open area. On Black Forest, relics can sit beyond a deceptively thin tree wall or near a secondary passage that players ignore while booming.
The real Easter egg is the information relics provide. If your opponent has collected three or more, they have invested in Monks, monastery upgrades, and map control. That can reveal a defensive fast Imperial plan before you see a single Imperial Age unit. Conversely, a relic protected by a neutral hill and a narrow forest entrance may be a perfect forward monastery position.
| Relic Situation | What It Reveals | Best Response |
|---|---|---|
| Relic near the center | Both players can contest it quickly | Send a Scout first, then escort a Monk with military |
| Relic behind forest or hill | Approach is hidden from standard vision | Use Scouts, Loom villagers, or a small escort to check the route |
| Several relics on one side | That flank may become the economic objective | Wall the approach and contest it before Castle Age |
| Opponent monastery near relics | Monk pressure or a relic boom is likely | Use Light Cavalry, Knights, or Redemption counters |
Monks move slowly and have only 30 hit points before upgrades, so never treat a relic run as a free pickup. In Castle Age, a single Knight can delete an exposed Monk. If the route is uncertain, use a Scout or Light Cavalry to reveal the area first. You can also place a waypoint through suspected relic territory during Dark Age scouting, then return once your first Monastery is complete.

Age of Empires II’s forest is not just decoration. Every tree cluster affects line of sight, pathing, attack angles, and the time required to reinforce a fight. On maps such as Black Forest, Arena, Hideout, and Michi, the most valuable “secret locations” are narrow gaps that turn a slow frontal attack into a sudden raid.
Black Forest is the classic example. The map usually presents thick walls of trees with a handful of obvious lanes, but generated terrain can contain small openings or unusually thin sections. A Scout moving along the outside edge may reveal a route that lets Villagers, Siege Rams, or a forward army bypass the main choke. These gaps are not guaranteed and are not always large enough for every unit, so test them with a cheap unit before committing your army.
Hills are equally important. Units attacking from higher ground gain an elevation advantage, while units firing uphill can suffer a damage penalty. A hill beside a forest entrance is therefore a valuable ambush site for Crossbowmen, Arbalesters, or Mangonels. It is also a terrible place to send a Monk alone. If you see an enemy army disappear behind elevated terrain, assume the fight is already tilted against you.
There is a practical way to find these secrets without memorising map files. Turn on your minimap view regularly, rotate the camera, and deliberately scout the border of every woodline. When your Scout’s movement stutters or takes an unexpected curve, inspect the tile boundary. Pathing oddities often point to a passable gap, shallow shoreline, or pocket of land hidden from the main approach.
Water maps add another layer. Shore Fish are visible food sources, but they can be hidden behind the edge of a fogged coastline. Fishing Ships can gather from them efficiently, and a player who finds an unclaimed pocket of Shore Fish may sustain a faster Castle Age than an opponent relying only on Farms. Do not blindly send fishing boats into fog, though: enemy fire ships can turn a “secret” economic route into free kills.
The Cobra Car Is Only the Beginning
Enable cheats in a single-player game, campaign, or private lobby and type HOW DO YOU TURN THIS ON. The message summons the Cobra Car, a rocket-firing vehicle that looks absurdly out of place among Knights, Pikemen, and Trebuchets. It is not a balanced competitive unit, but it is one of the most entertaining developer jokes in the entire series.
The Cobra Car is unusually powerful because it combines speed, ranged damage, and durability in a way normal Age of Empires II units do not. It can harass villagers, shred buildings, and outrun most conventional responses. The catch is that it exists for experimentation, not serious multiplayer strategy. Treat it as a sandbox toy or a way to make a campaign scenario hilariously chaotic.
Several other cheat codes reveal hidden units and jokes:
| Cheat Code | Result | Why It Is Memorable |
|---|---|---|
| HOW DO YOU TURN THIS ON | Creates a Cobra Car | Modern vehicle, rocket attack, completely wrong era |
| FURIOUS THE MONKEY BOY | Creates Furious the Monkey Boy | Fast melee unit with an intentionally ridiculous presentation |
| ALPACA SIMULATOR | Creates Alfred the Alpaca | A deliberately silly animal unit and a nod to the series’ humour |
| I LOVE THE MONKEY HEAD | Creates a VMDL unit | A bizarre novelty unit with an extremely memorable name |
| TO SMITHEREENS | Creates a Saboteur | Perfect for testing explosive siege-style attacks |
| WOof WOof | Replaces birds with flying dogs | A visual joke that changes the map atmosphere instantly |
Capitalisation usually does not matter, but spelling does. The flying-dog code is commonly entered as woof woof; the game accepts the phrase in lowercase in modern versions. Cheats can behave differently in campaign scenarios because the scenario designer may restrict units, population, or victory conditions. Save first if you are experimenting with a long mission.
There is also a useful non-joke command: MARCO reveals the entire map, while POLO removes the fog of war. Use them in a test match to study how a random map placed its relics, gold, stone, and forest corridors. That is a much better way to learn map generation than searching for a mythical universal relic coordinate.
Campaign Scenarios Hide the Best Scripted Moments
The campaign maps are where Age of Empires feels most like a handcrafted adventure. Scenario designers can place neutral units, trigger dialogue, lock objectives behind time limits, and make a seemingly decorative structure matter several minutes later. The hidden content is rarely marked with a glowing icon, so explore before you complete the obvious objective.
In Joan of Arc, keep an eye on the route between objectives rather than rushing directly toward the highlighted enemy base. Neutral settlements, allied units, and transport routes can alter the scenario’s rhythm, and losing a named hero or escort unit may remove options later. Joan’s campaign also teaches an important rule for every scenario: the safest path is not always the shortest one. Clear a forward position, protect your siege, and only then move the convoy.
Saladin rewards players who inspect coastlines and approach objectives with ships instead of assuming every fight must happen through the front gate. Naval control can change access to transports and supply routes. In Genghis Khan, the open terrain makes scouting even more valuable because a hidden enemy camp can sit outside the route suggested by the primary objective.
Some scenarios contain optional enemies, secondary settlements, or side objectives that do not appear until a unit reaches a location. Bring a fast Scout, Light Cavalry unit, or transport ship to probe the edges before triggering the next story event. If a scenario gives you a generous population cap and several minutes of preparation, that is often a hint that the designer expects a counterattack or a scripted escalation.
For the original Age of Empires and Age of Empires: Definitive Edition, the same principle applies, but the mechanics are different. AoE1 uses a smaller technology tree, different unit counters, and campaign scripting that does not map one-to-one onto Age of Empires II. Do not assume an AoE2 relic, Monk, or hill tactic exists in the first game. If you want to compare versions, the official Age of Empires Definitive Edition page is the safer reference than an old forum guide.
Small Details That Expose the Map Seed
Players often call unusual map-generation behaviour an Easter egg, but it is usually a clue produced by the seed. A woodline that bends around a gold pile, a deer herd parked beside a hostile starting zone, or a relic sitting just outside your Scout’s first circle can reveal how the map script distributed resources. Read those details early and your opening build becomes more reliable.
Deer are especially valuable because they let you delay Farms while maintaining food income. Lure them toward a Town Center or a Mill, but do not send the whole group at once. A badly placed Villager can push a deer into the forest or toward the enemy. Boars are more dangerous: the standard lure works because the animal has high food value, but an inexperienced pull can kill the Villager and wreck a Dark Age build.
Gold and stone placement also tell a story. An exposed forward gold mine encourages early pressure because it is difficult to wall safely. A back gold pile supports greedy technology or Monk play. If your second gold is trapped behind a thin forest, consider a small palisade and outpost before clicking up to Castle Age. A 25-resource Outpost is cheap compared with losing the economy that funds your next wave of Knights or Crossbowmen.
Use the replay system to turn these observations into a real advantage. After a match, rewind to the first five minutes and check when you discovered each resource. Did you miss a deer pack? Did the opponent reach a relic before your first Monk? Did a forest gap make your wall useless? Replays transform “lucky secret location” into information you can use in the next game.
| Map Clue | Likely Opportunity | Immediate Action | Risk |
|---|---|---|---|
| Thin forest between bases | Early raid or forward siege route | Scout it and wall the opening | Enemy can use it first |
| Back gold near a hill | Safer Castle Age economy | Place a defensive house or palisade | Hill can hide enemy vision |
| Deer near a side corridor | Fast food without early Farms | Lure carefully with a Villager | Deer may scatter into the trees |
| Relic beside an open lane | Monastery control point | Escort Monks with Light Cavalry or Knights | Opponent can counter-raid |
How to Hunt Secrets Without Throwing the Match
The best secret hunter is still a player who respects the build order. Scout the immediate resources first, then investigate unusual terrain. A common mistake is sending the starting Scout on a grand expedition while the opponent finds your exposed berries and kills your first Villager. Hidden content is valuable only when your economy can afford the detour.
For a standard two-player Arabia opening, use the first Scout to locate sheep and the enemy base, then sweep the likely relic and gold corridors on the return trip. Build your first houses before population space becomes a problem, place the Lumber Camp safely, and use a second Scout or Light Cavalry unit for deeper searches. In Castle Age, combine Monks with Knights or Light Cavalry instead of escorting them alone.
For campaign exploration, save before triggering a suspicious objective. Move one disposable unit ahead, inspect side roads, and watch for changes in dialogue or enemy behaviour. If a scenario offers transports, do not assume the obvious shoreline is the only landing point. A second beach may expose a weakly defended economy, a neutral settlement, or a safer route around a fortified gate.
Before launching a multiplayer match, check the official Age of Empires II: Definitive Edition Steam page for current version information, and use the official Age of Empires support hub if a patch changes scenario or mod behaviour. Community maps can add their own secrets, but those are separate from the relic and terrain systems in standard random maps.
Finally, do not confuse visual weirdness with a guaranteed exploit. A wall gap may be a genuine pathing route, or it may vanish when the map seed changes. A relic near your base may be a lucky spawn, not a fixed feature. The series rewards curiosity, but it rewards verification even more. Scout it, replay it, and test it in a private lobby before building your entire strategy around it.
That is why these secrets remain fun after decades. The Cobra Car and flying dogs are obvious jokes, but the deeper discoveries are practical: a relic behind a forest, a hill that wins a siege, an overlooked deer pack, or a campaign route that avoids the fight the scenario seems to demand. Look past the minimap’s obvious lanes and Age of Empires starts revealing a second game underneath the first.
