It's been a long time since I last worked on FLUT/UT2600. I got distracted working on a map editor and things happening in the real world .
I've picked up coding on UT2600 yesterday and added the sniper rifle. To give it a go, in the game's menu, press down twice to highlight the 'pickups type' setting and press right a couple of times until it says 'deltaforce'. Press fire to start the tournament. Press fire again for both players to accept the (randomly selected) map and start the match. Wait for a pickup to appear (a blinking box) and walk over it. It will give you a sniper rifle.
Now hold the fire button to begin aiming (a white reticle will appear) and (while keeping the fire button pressed) align your player either horizontally or vertically with your opponent. The reticle will 'snap onto' the opponent. Release the fire button to fire the sniper rifle.
The amount of damage done by the sniper rifle is based on how well you aligned your character with your opponent. The reticle's 'snap' behavior makes it harder for the shooter to judge how well his character is aligned, thus requiring some skill to perform a 'head shot'.
