Pro Great Sci-Fi story
Aliens, portals to other dimensions, oppressive regimes, oh my! This game brings a great flavor of dystopian sci-fi as you fight part of the rebel cause to deliver justice with your Gravity Gun to the many species afflicted by the evil Combine. Also Half Life ties in somehow with the Portal series which makes it even more awesome.
Pro Guns are varied and interesting
Almost every gun is fun to shoot and is distinct. The crossbow is super awesome for it’s power and the gravity gun offers variety in puzzles and what you can shoot with. Want to hit someone with an explosive barrel? Pick it up and throw it with the gravity gun!
