I won't go into detail...but drab.
Game blows...complete and utter waste of time and money.
Gameplay is horrid and contains nothing that made any stealth game (Splinter Cell, Thief, MGS) worth playing.
Graphics (Source engine) are ugly and wayyy behind the times.
Controls suck...though theres not much to do...just Ctrl to duck, left mouse button does everything else (climb, jump, shoot, stab, pull grenade pin, etc, etc, etc...)
Storyline doesn't suck...surprised? Well don't be...there literally is not one...nothing! No explanation of why anything is happening, we have no idea who the main character is or why she is doing any of this...I mean, theres no substance what so ever...and I'm not over exaggerating here.
Overall it gets a 1/10...and only because the audio is pretty decent, and that is all.
