i may have just experienced the most madness inducing custom gamemode on the face of the earth
UberUpgrades.
It's a large pile of forget where people can make all the OP guns and resistances they want: by killing everyone
it supports MVM and it's a insane gamemode where anything can happen
go play it you frikin fricks
Played it earlier.
Went as scout and used the soda power. Maxed out all basic defences and raised standard damage to about 30%
Got every 1 point upgrades on the gun, dealing fire, crit, etc. I increased health to 950 and had 100 regen
Got 2 in ammo regen
raised damage to about %1300 then got the fast firing spec.
Shot 13 rounds with about 40 pellets each extreamly fast with an almost instant reload. To unprotected peaople, i did about 1000 damage a shot.
i also got health on damage, combied with fire, so i was not only getting regen, but also 15 health a shot w/ fire
It was pretty op, not counting my knockback. I was nearly invincible except for 2 people who only had damage upgrades and if someone was annoying id lock them in a corner.
After that I got defences but did high upgrades on the cleaver
