Quoted from A. Distler:

Left to Frag Alone is dedicated to bringing the best quality gameplay to QuakeWorld. To achieve this, the following modifications have been made :

Level changes :

• Most healths are the full 25 point, rotten healths (15 point) have been converted to regular.
• Red armors are usually replaced with yellow or a Rocket Launcher.
• Large ammo boxes are usually replaced with small.
• All non-game effecting entities have been removed. This includes torches, light globes, ambient sounds, exploding boxes, etc.
• Most secret doors removed.
• All powerups removed.
• Platforms and Doors have been speeded up.
• On some levels (dm1, e4m3) certain structural changes have been made to give the levels a faster paced layout.

Progs changes :

• Upon respawn, all players start with the same items :
  • Nailgun, Super Shotgun.
  • Ammo for each of the above and 5 rockets.
  • Green Armor.
• After being killed, a player is allowed a few seconds to rest, after that time the player is forced to rejoin the action.
• Rocket and Grenade Launcher do slightly less damage.
• Super Shotgun and Axe fire quicker.
• Backpacks heal the player half way to 100. For instance, if you have 33 health and pick up a backpack, you will have 33 health healed.
• All armor when picked up acts as green armor. Yellow and Red will just give more.
• Super healths give 50, but will heal player to 100 if they are below 50 when touched. Also restores armor to 100.
