Adventure Gamers: Portal 2 Review

Improved in almost every way, Portal 2 is an incredible follow-up to what was already an amazing game.

Pros:

Great puzzles; funny writing and superb voice acting bring memorable characters to life; challenging co-op campaign is an excellent addition; improved visuals; twice as long as the original.

Cons:

Very few, if any. Replayability is a bit limited; Steam activation required, if that matters to you.
