YES, been waiting for one of these
Engineer:
•Monkey Wrench, Does less damage to enemies, is 10% more metal efficient (100 metal = 110 upgrade), and a critical hit on a sentry is twice as efficient (100 metal = 200 upgrade points)(replaces wrench)
Spy:
•Poison knife, poisons enemies for as much as burning does, except at 1/2 the speed. He can also use this to poison medi-kits, which will also give enemies the poison damage. The poison will last for 15 seconds before it disappears, and the infected medi-kit will give off a green glow every 5 seconds, just to be fair.(replaces butterfly knife)
•Tazer- Like thing: Shoot it at sentries, but it takes numerous hits, as the electricity is powered by a weak battery. 3 Hits will take out a level 1 sentry, 5 for a level 2, and 7 for a level 3. This can also hurt enemies very slightly, and stun them for 2 seconds. (replaces electro sapper)
Soldier:
•RPG: Slower rocket that does slightly more damage, and has a slightly bigger explosive radius. Flings enemies farther.
