Portal 2

Now then, portal 2. the BEST game ever. EVER. it took me AGES to finish. here's a hint: don't play 2 player mode until you finish singleplayer. it makes it more fun.

STORY:
THE BEST. just full of twists and turns, but 9 3/4 out of ten because of the sad ending.

DIFFICULTY:
10 out of 10 really hard.

OVERALL: 10 out of 10.
AWESOME!
