The good: excellent graphics, sound, story, blending of cutscenes in the game.
The bad: nothing really original, short first person, and my issue is the AI and their close to perfect aim. In a tactical shooter its off putting to get hit that much even while being hidden. AI aim is flawless from any distance in any situation. Yes they are dumb and predictable, but manage to place a few bullets in you from miles away while running. There is almost no way you can flank them or surprise them when alarmed. Its ok in Serious Sam but not in a tactical shooter.
This game sucked. Levels too dark making it too hard to locate enemies, wave after wave of enemies, stupid breaching with slo-mo kills, and not one but two awful driving missions. At one point I thought I was playing need for speed. Waste of an afternoon.
