It's a fine game though a little outdated and it is clear that it was a 2009 (lot's of bloom, not a lot of contrast)
I got stuck in a stealth section and do not like how it is done there

It may not be the greatest masterpiece or a story with profound emotions but it's overall a great time.
The difficulty curve is excellent, starting easy and progressively being harder but always being just, just enough to be sometimes in the edge but not to hard to be frustrating

It's fine for passing the time on computer class but there is little progression on the game. Doesn't beat Counter Strike 1.6
