The Rescue Ranger
Engi Shotgun
Repairs buildings from a distance with special bolts, requires no metal to fire. Press mouse2 to pick up buildings that you have a line of sight to for 130 metal, no limit on the distance.
The Vaccinator
Medi-Gun
You can hold up to 4 ubers that last 1/4 as long as the original medi-guns. Ubers charge 50% quicker. -66% overheal build rate.
The Loose Cannon
Demoman grenade launcher
You can charge cannonballs so they can explode early, unlike the stock launcher. You can hit players two times as well, once with the normal hit and the second with the explosion from the cannonball resulting in 140-180ish damage. Pushes players back VERY FAR when hit by the cannonball. I think the projectile speed is a tad slower on this than stock. Grenades do -50% on contact with surfaces resulting in much less damaging spam.
