As a rule, most FPS games have a generic weapon: the moderately-powered, usefull in most situations one that you get more ammo for than any other weapon. Invariably, it is not powerful enough for one-shot, one-kill on most of your enemies. This means whenever you confront one of those enemies you have a choice: stand there and blast them until they go down, or play peekaboo with ducking, finding cover, retreating, etc. Either way you can take a lot of damage: The only thing more frustrating than an enemy that keeps shooting you while shrugging off a dozen “flesh wounds” is one that always, always beats you to the draw when you have to re-acquire your target eight or nine times. So how do you deal with this situation?
Grenades.
Nothing means not having to say you’re sorry like grenades.
All in all, in FPS, I am in favor of a good camouflaged and covered position from which I can nibble them to death with an endless series of well-aimed shots. Ideally, you just aim at one arm poking out from around a corner.
I try and get into a position where I can fire and take cover without having to change my aim. So ideally I’d be behind a wall or something, peek out and line up for a shot, take the shot, then take the cover just by moving my body, not my head/look/aim. Then I can just move in and out of cover as required. This assumes the other guy isn’t moving much.
Yes, I’ve shot people to death in the toes before.
Yes, the “Elbow Execution” is my favoured technique. Failing that I run in like a retard, throwing highly-explodable ordinance (grenades, rockets etc.) and spamming on the health-packs like there’s no tomorrow.
