Team Fortress Arcade
About
Team Fortress Arcade is a game created by Eric Ruth, who had previously made side-scrolling versions of Halo and Left 4 Dead. It is a side-scrolling game in which the player, or players, take control of any of the 9 BLU classes from Team Fortress 2 and progress through 9 levels, each of which has one of the RED classes as a level boss – as well as a secret tenth boss which ties into the Portal franchise. The game supports up to 4 players at any one time.
According to the developer in the interview, he states that he "intends on updating the game in a couple months with some new modes, difficulty challenges, a player VS player match-up and yes, online co-op." When guest hosting on KritzKast, he announced that he had been acquired by a gaming company and thus would not be able to continue support for the game for copyright concerns.
