Any shots you see from 2001 are incredibly misleading.
They were aiming for TF2 to be a very realistic wargame - but of course several other FPSes were released in the meantime that totally bled that market niche to pieces already (Battlefield et al).
It feels very toystorish now. And, damnit, I kinda like the looks.
From left to right: Pyro, Engineer, Sniper, Spy, Heavy Weapons, Demolitions, Medic, Scout, Soldier.
God this is soooo gonna kick ass!
