Most are humanoid but there are also fish, spiders, Targs and guard dogs to spar with. On the toughest difficulty level the game is brutally hard in parts. Speaking of which, there are four difficulty levels ranging from Ferengi to Klingon. Even the best player will find Klingon a serious challenge as the AI is aggressive, alert, and packs a punch. But even on Ferengi level you can get caught unawares and ambushed by several foes.
Controls are mostly standard fare.
You can run, crouch, jump, strafe and even jump quickly in any direction to avoid fire. For the most part I enjoyed the game and it worked as advertised. There were a few annoying bugs though. If you reload a saved game the first powerup will get used automatically. This may mean you float off in space if you were on the hull of a vessel or that you waste a communicator or tricorder.
