what kind of puzzles can scientists solve?
How to unlock a closed door?
And speaking of closed door, remember, how Boomer blew up a door with a high explosive?
Demomen are also needed.
so it's like this
Demo squad
Weapon: MP5, 9mm pistol, explosive charges
Armour: heavy (cause they carry explosives)
Strenght: they blow
**** up, like obsticales.
weakness: their MP5 is shitty, so they won't last long on their own.
