This is an addicting game. Loved the slow mow aspects of the game, the weapons, and the control system is awesome. Doesn't take long to learn. My gripe is the when weapons are available and how much ammo is available. I think if there was more ammo available, the levels would be more beatable. Would have helped too if there were more grenades. Sometimes it was aggravating when you dies too early in the game. It also needs more variety when it comes to locations. Would be nice if there were more urban or outdoor environments. And more cover to hide behind!!
Some levels you could get way too exposed. Definately more tables, desks or other solid objects like potted plants sure would help. A soldiers ally is cover. Sometimes you have no option except to John Wayne your way through. Overall they did put the scary moments at the right time. Definately like playing the Ring with a militaristic aspect. If you expect to finish on the 2 highest fifficulty settings, I suggest lots of caffeine and cheeze puffs. Because it takes a lot of patience and perserverence. Hopefully the next two games in the series have improved on the flaws that this game has. Overall, it does keep you coming back for more. You can't say it's no challenge at all. (as long as the Amatron levels get fixed).
