Quite original i gotta say !
And i really like the fact that the game spends no time waiting around, once you hit that gong, it's on !! And its total mayhem, The controls felt quite responsive my only gripe would be that the aiming can feel a tiny bit imprecise and this makes the game a bit too hard considering the non stop chaos that's going on, other than that not really much negatives.
The presentation is awesome, and i liked the little details like the occasional "wilhelm scream" classic :p ! not to mention the reference from the game title itself.
Just tweak it a bit for the aiming to balance it better but other than that really "Can't touch this ... " * mucis rolls* Well done :) !
