it turns out this game does work on my mac, cool style, it is like doom with the 3d and sprites but it plays and looks like halo on the OG xbox, the only minor issue is the sword looks like to can reach longer but find myself always needing to hug the enemies to make a hit, and sometimes trading blows.
but with the excellent life recovery mechanic it is not really a issue and maybe more that I am a sucky player, hah hah.
