It’s an ultra Rae item from a robot expansion mod’s it when inactive it is a multi tool with all the tool box fiction’s and more it is an anvil, hotplate,wrench,chem kit,can make zombie slaves with high enough skill and is a gun/clothing repair kit, and a crowbar when activated it follows you as long as it has line of sight,zombie attack it and it is VERY fragile to the point that it can get extremely damaged by a zombie child easily, it is extremely rare and by it’s description that says it is used by workers in mines or oil rigs I think so probably you find then on mines or labs,also it is huge having 50 liters of volume and about 10 kg (I use the metric system because I like it ;’-’
but yeah probably the mod item ever, I really don’t see drawbacks on it as long as you keep it away from zombies when active it can’t carry stuff also,in the deadpeople tile set I has a cute smiley television instead being an bizare lunar tripod
