I played the demo and I liked it.

One major difference compared to other shooters like MOHAA is that you can't just run in with an SMG and slaughter the badguys. You take just as much damage to die and you must be careful when moving into rooms, etc.

Some things I liked are:
1. one guy can't carry a whole arsenal, so you have to divide various weapons and equipment among your team
2. more items to use (lockpicks, AP mines, AT mines, etc)
3. ground vehicles that you can mount and dismount freely.
4. big maps and good storyline
