stupid idea time go~
Bastion has Gods and Halo has Skulls, why not do our take on the whole "inflict a higher difficulty on yourself for bragging rights" kind of deal? one that buffs hale's foes and nerfs hale himself?
Finish them fast: everybody has a health regen buff (+1 health regen per tick?)
Aftermath: killed foes leave behind a demoman grenade on death.
Honorable Hale, Point: Hale cannot cap, but he can defend.
Honorable Hale, Rage: Rage takes longer to build up, except under sentry fire.
Apocalypse: remember towertop's moon event? this is that, but with a time limit that rebalances itself to the amount of players there are, and if hale cannot kill them before time is up, it's considered a stalemate instead of a "win", as everybody is slain. (might need some balancing if implemented)
Rage Won't Help You: raged players can still defend themselves with melee weapons, and automatically switch to them when raged.
Toughed Up: Hale's foes start with normal overheal max as their true max hp through buffs, but medic's mediguns lose the overheal function. (might be tricky considering how many items alter max hp)
