From BigPackets Game Hacking Wiki

Nullcore is a VIP Hack provider made by V952.

Nullcore is known as the CitizenHack of TF2, because a better and public alternative is available (LithiumCheats)


At first, they only had a Half Life 2 Deathmatch hack.

After a year or two, V952 ported it to Team Fortress 2 and added some magic aimbot prediction

It had many wars with LithiumCheats and Rud.
