This addon is an edit of gg_knife_pro which comes standard with Gun Game v4. It was created by the Gun Game coding team (Cagemonkey and XE_Manup) and all credit is due to them.
This addon makes two configurable options for Knife Pro. 1. Whether or not to gain a level from knifing. 2. Whether or not to lose a level when knifed. 3. Option to gain level if player is on level 1 when leveling up is enabled.
This was created because I love being able to steal levels, but have always refused to use it due to a distinct hate of players who only run around with knives trying to level.
