Enemy Territory: Quake Wars
ETQW - Common abbreviation
As a successor of Wolfenstein: Enemy Territory focuses on objective driven gameplay rather than just capturing flags like you do in the Battlefield Series. This means that on every map one team needs to fulfill an objective while the other needs to guard it. For example on the map "Valley" the GDF needs to build a bridge, then drive a MCP over the bridge to a nearby outpost, hack a Strogg-shield so that the MCP can fire a missile into the Strogg base so that the GDF can enter it and destroy a generator.
To make it even more complex, most objectives need to be completed by a specific class. On each side are five classes and each class has special abilities. The engineer for example can build the bridge on Valley, repair damaged vehicles or deploy identities while the Field Ops supports his teammates by handing out weapons and deploying artillery systems. Since the maps are all pretty big, you also have access to several kinds of vehicles ranging from little quadbikes to helicopters.
Unlike most multiplayer-games, the teams in Enemy Territory: Quake Wars don't just have a different skin but are actually completely asymmetrical balanced from classes over weapons to vehicles. This means that while both teams have a medic, they both function differently. The GDF medic for example behaves like every other medic by instant reviving his teammates but the Strogg technician needs a few seconds before his dead companion is alive again. To balance this out, the Strogg technician can turn dead GDF soldiers into spawn hosts. So if he dies, he respawns at such a host (if it hasn't been destroyed).
