What this game reminds me of is Quake4. Sure, there are differences, but still. Similar mentality of design. Pity though Quake4 is a meh game more than it should be. If someone wanted to check out Quake4 nonetheless, I have some IDtech4 engine config tweaks - pure text, without any install - that max out the game a bit for modern PCs. Same goes for other IDtech4 games, like Doom3 standard edition or Prey .
