HL2 too easy? Fear not! Where there's a nerd there's a way.
Minimalist Gordon: USP + crowbar only. No ammo cheating.
Darth Gordon: Manipulator only.
Dirty Gordon: .357 only but with no reloading (ie. you die, it's game over).
Pinup Gordon: crossbow only. No reloading.
Tactical Gordon: no hud.
All on hard difficulty of course. RPG to be used only when situation demands it.
