Should you buy Syphon Filter: Combat Ops? Yes. It's ten bucks, and even if you only create two or three maps and play'em online, the fun and frantic missions should cover the cost. This game's deep and easy to play, but my only worry is how long it'll be fun to keep playing. If the install base doesn't beef up, you might be left with a worthwhile title only a few fans are using at prearranged times. It might be hard to just pop into a game while you're waiting in your doctor's office.
