Gonna be a short one.
Graphics are pretty damn good but can be confusing to decide who is an enemy and who is a tree! (You'll know what i mean) story is longwinded and confusing at times, achievements are poor as pretty much everything is online only.
Do not buy it if you are looking for the same sort of turok from n64. Its a completely different style and gets pretty boring pretty quickly.
Pinning people to walls with the bow is only fun for so long.
And the online play...you would be very lucky to find anyone playing it. I found noone on 4 seperate tries!
