Hitting my inbox on Friday night was word from the ioquake3 project of a new game update/release being powered by this widely-used open-source id Tech 3 project. The game? Turtle Arena. While I'm not exactly a gamer myself, when hearing a title of "Turtle Arena" and being powered by the ioquake3 engine, I had to check it out. It sounds like a racing game... Or is it a Quake 3 mod where you're a turtle shooting water? Or is it a race to grow turtles? It ended up being none of the above.
Turtle Arena is described as "a free and open-source third-person action game" that is multiplayer-focused with different game modes, and even has split-screen arcade-style gaming support. There's also support for AI players, or rather, AI turtles. It appears that Turtle Arena is basically trying to be a game that's an open-source version of the Teenage Mutant Ninja Turtles.
as visually advanced as some of the other ioquake3 games. Modifying the ioquake3 engine into powering a third-person action title is also interesting, but sadly with its physics support lacking the game-play is quite constrained, but likely enough to entertain a young child.
