its not that bad.
It has decent graphics. The story is somewhat cliche but its ok, combat is fun but it gets repetitive since there IS A LOT OF COMBAT. Its a Gears of War game with Enemies taken from Xcom (you will see almost all the enemies from XCOM enemy unknown) with a super-slow-motion pause to give orders to your partners
When you are not fighting you are just running through nice looking corridors that have nothing to interact with.
I cant remember how much time it took me to finish it but its long enough (and maybe a bit too long because of that thing of it being repeatitive)
It has been really cheap lately, like 5 bucks. For 5 bucks i think its a good purchase.
It wont blow your mind, but its a fun ride
