Man i just got the game today. The gameplay is blowing my mind!!!! I really like the reloading on this because its all fast and I get to control my own squad. Also i can act as a medic and heal my troops. Its great because i can hold healing items to heal myself. Plus the melee is strong and kills enemies in one or two hits. With the Adrenaline it lets you be invincible for short amount of time, plus with doing damage extra and have unlimited ammo during that time.
If you guys have played it, tell me about your experience. And how do you like it. If you haven't heard of it. Then get out there and buy it now.
