ET is a full free multiplayer first person shooter game. The game was originally going to be a retail expansion pack for Return To Castle Wolfenstein but the project was cancelled and the good folks at Activision decided to give it to us for free!
It’s a team game; you will win or fall along with your comrades. The only way to complete the objectives that lead to victory is by cooperation, with each player covering their teammates and using their class special abilities in concert with the others.
