Only... Wow. Great fun multiplayer, Can't wait to hear what GLaDOS says next...
The game makes you feel both brilliant and idiotic at the same time. The review on the main page says it's an action shooter - I don't know what game they were playing, but it wasn't the same one I was playing. This is a puzzle game. It's all about brains, thinking, planning, problem solving, and occasionally an action hero stunt. It's the first game I can think of where I found myself thinking, "it's fun to die!"
The female robot (GLaDOS) is so snarky she's wonderful. We couldn't wait to see what snotty thing she would say next in her oh-so-sweet, calm and friendly voice. Wheatley truly earns his place as GameInformer's #1 Dork of the year, but, at the end, it's hard not to feel a bit sorry for him.
You'll have so much fun playing this game, you won't even feel bad about trying to kill GLaDOS.
Twice.
You Monster.
