Portal 2 is absolutely amazing. The game includes new puzzles, which are far more challenging than the ones in Portal. Two new additions to the puzzles are lasers and the repulsion gels. Portal 2's story is far longer than its predecessor, Portal, and also includes a new game mode called "Co-Op". Co-Op is a game mode where you solve portal puzzles, but this time, with one of your friends. It requires hard teamwork, and I highly recommend having microphones to communicate easier. Portal 2 is worth absolutely every penny you spend on it. If you found Portal to be a good game, Portal 2 will absolutely blow you away.

I'm amazed that a game like this has been made Free to Play! Team Fortress 2 is such a wonderful experience. All I can say is take advantage of it being free!!

Not your ordinary survival game. It required teamwork...and brains. Instead of going from point A to point B killing specimens along the way, your in an area..fighting waves of specimens. The game gets harder at each wave, ending with the final wave, The Patriarch, which is bascially the boss. Extremely fun to play with friends, but still as fun playing solo.
