So I was reading about Team Fortress 2 and they talk about the new engineer... Primary Weapon: Shotgun Secondary Weapon: Pistol Melee Weapon: Wrench Other Weapon: Construction PDA Hmmmm i think valve needs to share the love on where they are getting this from.... :p
TFC building wasn't ammos based. the 200 was building and repair material, used to make Dispensers, Sentry Guns (and upgrade them), Teleporter Entrance/Exit, and any mod engineer builds, like the Bounce Pad, and Multi Gun. build/repair material could be used to repair any stock TFC engineer builds, and some mod builds.
This smells of lawsuit to me... Only kidding. It's almost certain to be a coincidence. If they had construction calculators then I would get suspicious.
