Good groundwork
Fun brawler at the core. The testosterone filled humor and simplistic story line make the game funny and enjoyable. The music is solid and the controls are mostly responsive.
Now the nitpicking cons: Basically summed up into expecting more. Each level plays nearly identical to the other. The weapon variety is good but not great. Maybe doing achievements could unlock additional weapons. Secondly, sometimes there were issues were I was lined up to hit an enemy and didn't connect. Also, why were there paved roads towards the middle of the screen that I couldn't walk all the way up to? Also, another suggestion would be a middle difficulty level.
Overall, I enjoyed this game and sure others will but that's hopefully constructive criticism. A sequel with those improvements would be stellar.
