This is perhaps the finest game of all time. I was a beta tester for the unreleased windows version of this game. It can be played one handed using just the cursor keys and it puts you in the "zone" where you stop thinking and just feel. Plotting your route and your gun orientation is all that's required in levels that are full of hazards and rewards. The game design is exceptional and it runs on a potato. A magnificent game, and I've put in over 1,000 hours on the beta. Llamasoft Giles and Jeff are the gods of game design and zone gameplay.
