There were lots of cool things in this but also some annoying flaws.
The coolest thing in this was the fire. Its pretty cool how many different ways you can use fire to take down you enemies. One other cool thing...at least to me it is...is when you have to stabilize yourself, when doing so you either pry out a bullet with your knife, stick a pack of lit matches in you arm, crack a wedged bullet out of your elbow, or bite a bullet out of you forearm. The weapons in this are pretty cool too because you can up grade existing ones by either increasing reliability, expanding ammo capacity or increasing damage. There are a variety of weapons from sniper rifles to special weapons like the flamethrower. There should also be a warning because of the addictingness. You will not be playing this in short bursts.
If you liked oblivion and call of duty games you should like this a lot.
