It's basically Operation Carnage ('96 - DOS) on steroids with a somewhat nonsensical story tacked on.
[it's supposed to be a remake of sorts]
Think Smash TV without the dual sticks, which IMO is a better way of describing it. Well, cept you can also piledriver enemies.
There's a verity of difficulty levels, and the curve between them is pretty much spot on however goddess difficulty takes no prisoners - there's also an alt ending on goddess.
It's short, only 4/5 levels (one's hidden).
Enough description, it's a small download so give it a go.
<Erf> SkulFuk: gf just made a toilet sniffing joke at me
<Erf> i think
<Erf> i think i hate you
I downloaded it, completed it in Combat mode
went onto the 3rd difficulty, found it insanely hard after pile driving a few enemies, got bored and decided to go on hardest difficulty.... Well.. Thats my life goal now
