I've been recently playing Urban Terror, which is a multiplayer FPS game built on Quake 3 engine, and runs across Mac/Linux/Windows. Are there more such games that are

  • free
  • run on immersive 3D engine [not a Flash/HTML5 game]
  • belong to action-adventure/RPG/RTS/[insert your favorite] genre
  • possibly multi-platform [not must-have but a nice-to-have]


  • This is an awfully subjective (and a list question). Same rules as other list questions apply here. (See apple.stackexchange.com/questions/82/… for example)

  • @Chealion While I agree that it's a list question and following those rules would be nice, is it really subjective? Seems to me one could objectively list all free, 3D-engine driven OS X games. The only possible subjective aspect is determining a genre…

  • @Chealion ignoring, of course, the big argument between "free" as in beer and "free" as in open-source. :) But that could be fixed with clarification from @rubayeet.

  • @Chealion - I admit the question is subjective in the sense that it's tricky to distinguish a single correct for such questions. However, my curiosity is genuine. I'm not just trying to list out a few apps(that I know of) in the answer thread(as in the question you linked). I'm trying to find out such games with the help of the community.

    @ghoppe: Cool is subjective - the community here has said they want to allow list style questions like this - I just wanted to reiterate the rules that help make the list question on Apple.SE worthwhile (and allow the OP to add them to the question)

No discussion of free FPS games on the Macintosh can be complete without a link to Aleph One.

And of course, there's that recruiting tool, America's Army. Version 2.5 was available for Mac OS X. I guess version 3 isn't being developed for Macintosh yet…
