HA!!!
I beat it... why is easy so hard? Unbalanced like hell... starting off u get screwed, but near the end when you get the machine gun upgrades you get super strong and can do everything by yourself. But I do like that as rounds keep going, more of your "COMMANDO ASSISTANTS" spawn so it helps when you take down the enemy turrets and are just trying to finish off the base. But all in all a good game. (more upgrades, more commando's, and better variety of enemy's/maps)
