Creeping

Stealth is an oft-overlooked resource in gaming. So often you are just required to kill and kill and kill (and here you still have to kill a bit... well, quite a lot actually), but there is a suggestion here that avoiding the kills might serve you well.

You have a silent knife kill at your disposal, and a selection of stealth movements too. You also have some big bad guns to do the killing with, but that's bad and wrong. Oh, and you can teleport too.

Use the WASD keys to move and space to jump. press 'f' to perform a silent kill and or hold it to shoot, using the mouse to aim. Press shift to teleport and hold 'r' to pick up a weapon.

The movement controls are quite annoying... so take a bit of time to get used to them in the simpler levels.
