Well, you can count it as an addon to BlazingHotBosses, but it didn't fit with the original mod, so it's separate. You DON'T need to have Blazing Hot Bosses to play this mod.
The mod adds 2 new weapon, a boss, and an enemy. It also features russian localization. That's it. I tried recreating sans as hard as i could and i think it turned out pretty well.
Sans will use following attacks:
-He summon bone circles when you are too close.
-He will summon Gaster Blasters, they shoot you with explosive lasers, but their health slowly depletes.
-Sans will constantly shoot you with bones, and make them rise from the ground in a line like pattern.
This mod was made using MCreator
