If Apocalypse wasn't hard enough for ya

Or if you have a death-wish

Monsters are taking over!

Around 5 times damage and health, these guys are tough!

1.4 times faster, you won't outrun them for long...

Regeneration that rivals yours, battles of atrition are no longer an option to survive in this doomed world.

Hero, will you survive, or will darkness prevail?

(i really don't recommend trying this by itself, it's hellish)
