WASD is universal. It controls how the camera is shifted in the space. The mouse gives precise rotation. If you’re doing a driving or flying game then a keyboard is clunky.
You haven’t experienced it enough then. You don’t even need to know touch typing. It’s just movements to appropriately react to what is on screen.
The muscle memory is the same for every game because they’ve mostly standardized the controls.
shift, A, W, D, space is the “home row” for gaming.
Ring finger goes on A (left)
Middle finger goes on W (forward)
Pointer finger goes on D (right)
Thumb goes on space (jump)
Pinky rests on shift. (sprint/other)
Pinky: is free from WASD and can use ctrl, shift, capslock
Thumb: If X, C, V, ALT need to be held then it should be something you wouldn’t use with space.
That’s why in ET I liked using X for prone and C for crouch. I would always configure other games to do that.
Ring/Middle/Pointer: Any other key is usually a momentary press for a toggle or use key. Then you reset back to “home row”. Q, E, Z, R, F are all pretty accessible and require a brief interruption of WASD.
V, B, G, T are usually game interrupting commands such as chat/vocalize/map because they’re too far from WASD. Anything further right is the same and available for custom scripting.
If you struggle with pressing 1-5 for items, there’s also the less efficient scroll wheel. I usually bind 4 and 5 or crouch to my extra mouse buttons.
Anyone in the FPS background thread should be able to describe all of this off the top of their head.
This finesse is a skill that can be worked on with any FPS, so choose whichever one you enjoy most. This is also why this genre is probably one of the most popular. There’s not a whole lot to relearn like an RPG or RTS would have. Being level 50 in Age of Conan won’t do anything for you in World of Warcraft. Playing Rise of Nations well won’t do anything for you in Starcraft 2. Personal adaptation to the controls is a large part of FPS and it carries across them all. That’s why I’m so fascinated with Brink because there’s also character leveling. So even when you move on from one game, you still have keyboard and mouse finesse to apply to the next one. L4D is very intriguing because while you still benefit from all this, it’s not quite as important. And Brink is doing something similar.
