Treaty is a game mode which was first introduced in Age of Empires III: The Asian Dynasties, and then used again in the Extended Edition of Age of Mythology and in Age of Empires II HD: The Forgotten.
In treaty, the player who serves as host to a game may specify a time period in which players are not allowed to wage war on each other, thus negating rushes.
Age of Empires II Edit
Treaty is an option for the host of a multiplayer game to set up for a match, available from The Forgotten expansion on.
With The Forgotten, there is a treaty option in the game's lobby settings. It can be set so that player cannot attack each other for the first hour. All players will temporarily be set to ally with each other.
With the treaty mode active, players will notice a yellow box around the base of each player. Before the treaty ends, this is a "no build zone" for all other players. It prevents players from hindering each other by building in other player's bases and severely hamper their economic growth, e.g. by walling their Town Center.
Age of Mythology Edit
Choosing the treaty mode prevents players of a game from attacking each other for a set amount of time (15 minutes). It also prevents people from building too close to starting Town Centers.
Treaty is available as a scroll option from the game mode dropdown menu when setting up a random map game.
Age of Empires III Edit
During Treaty, players may create Blockades, in order to prevent the enemy from receiving shipments from their Home City. However, they cannot construct structures that are way too far from their starting Town Center to avoid abusing base defenses and limit offensive expansion.
This also extends to Trading Posts; distant trading sites cannot be built upon.
There are five treaty selections in-game: The player may set the treaty period to 10, 20, 30, or 40 minutes, and there is also the 'Treaty - No Blockade' mode. In the latter, the treaty period draws for 40 minutes, but without the capability to create Blockades.
- Treaty is not technically a game mode in the Extended Edition, but instead an scroll option, meaning that it is interchangeable with Supremacy, Lightning, and Deathmatch.
