Since when I saw that Spyper was made, I searched up if anyone has made the Heavy.
And from what I've seen, nobody has, so I decided to make my own!
The Heavy encounters your team, and he already knows there is no other way out.
Class - Heavy
Health formula - (((780+n)*n)^1.04)
Lives - 1
Rage damage - 3500
Main Weapon - Fists Of Steel
Abilities:
Rage gives a temporary Reserve Shooter and a permanent Sandvich Launcher (acts similar to Loch-n-Load).
Charge teleports the boss to a random player.
Has an invisible thruster (from https://forums.alliedmods.net/showthread.php?t=316837)
