There was a game i played. It was a top-down shooter game. The character you played with was pumpkinhead or you could choose characters and he was one of them i cannot remember. The game is similar to Crimsonland.

Sounds like Restless Night

No thats not it. It doesnt have pixelated graphics.

I think it can be one of the R.I.P. games:

(if I'm correct, all three has this character available)

Happy I could help :)
