Get ready to Rumble!
Atomic Elbow
Think you're a legendary hero? How adorable .
Now prove it in Sir Whoopass™: Rumble! , the new DLC that takes the familiar Sir Whoopass mayhem, stuffs it into a monster-filled blender, and sets the blender to “questionable life choices.”
Fight through waves of enemies, grab ridiculous amounts of loot, pick upgrades that turn you into a walking disaster with spinning chainsaws, and see how far your heroic ambitions can carry you before the game reminds you that you are, in fact, extremely punchable.
WHAT'S IN THE MEAT GRINDER YOU MAY ASK?
- ROGUELITE, SURVIVORS-STYLE MAYHEM Fight increasingly chaotic enemy crowds and turn a desperate scrap into an absurd power trip.
- RANDOMIZED RUNS Encounters change from run to run. Learn to adapt, because your carefully prepared plan is about to meet a over-sized orc and grumpy grandma.
- UPGRADES! BECAUSE DYING THE SAME WAY EVERY TIME IS BORING. Pick powerful upgrades, stack ridiculous bonuses (and hats), and turn yourself into an unstoppable killing machine. Or at least a slightly more expensive corpse.
- USE YOUR HEAD. PREFERABLY BEFORE LOSING IT. Crack puzzles, uncover secrets, and try to stay alive long enough to enjoy your own genius.
- CO-OP CHAOS Share the danger, split the loot, and finally settle the age-old question: which one of you is the liability? Don't worry, friendly fire is optional for those of you who chews bubble gum.
A FEW SIGHTS FROM THE RUMBLE ARENA
SO, READY TO RUMBLE?
Grab your weapon, gather your friends, and throw yourself into despair.
You will die. You will restart. You will absolutely blame the devs.
And then you'll play again.
Sir Whoopass™: Rumble! - the new DLC for Sir Whoopass.
OUT NOW!!!!1
As always, have a whoopingful time!
The Sir Whoopass team.
