With permission from PillowBlaster, I bring thou the RUSSIAN POWER on the planes of Zandronum, allowing us to play multiplayer with it with nice proper netcode and shits. Have fun.
If you are asking yourself right now "what the hell is a russian overkill", you honestly had no life.
Spoiler: what the hell is a russian overkill (Open)You need Zandronum 2.0 to run this. Please note that not everything has been properly tested, and while this generally works online, there may be bugs.
Note: if you are hosting this, compat_clientssendfullbuttoninfo MUST be set to True to enable combos and certain altfires.
Note: I did my best to optimise the weapons, but some of them just refuse to properly optimise. Most of them are okay, but some are laggy. Examples include Katuysha, Libra, Yamato, and a few others too. Please ensure you have more or less capable internet before hosting this.
