Every R.E.P.O. monster and a Minecraft army fight in TABS, and you can play Steve like real Minecraft.
Every R.E.P.O. monster and a whole Minecraft army join Totally Accurate Battle Simulator. Solo.
The R.E.P.O. faction: all 29 of R.E.P.O.'s monsters plus the Semibot. Each one is R.E.P.O.'s real model on its own R.E.P.O. skeleton, moving with R.E.P.O.'s own animations, sounds and health, read from your copy of R.E.P.O. They attack the way R.E.P.O. plays it, with the same animation, timing and damage:
The Minecraft faction: Iron Steve, Netherite Steve (shield and Totem of Undying), Zombie, Skeleton, Creeper, Witch, Piglin Brute, Piglin, Iron Golem and Warden. They use Minecraft's own attacks and numbers, with skins, items and sounds from your copy of Minecraft.
Play as Steve like real Minecraft: take control of either Steve and you get first person, Minecraft's HUD, hotbar and full inventory, an offhand (C swaps), and hunger with food: healing costs drumsticks. You can mine, build and fight. Netherite Steve also carries ender pearls, an Enchanted Golden Apple and flint and steel. Build an obsidian portal frame and light it: the Nether spreads around it and piglins walk out.
Needs Totally Accurate Battle Simulator, R.E.P.O. and Minecraft: Java Edition. Nothing from the three games is included: the mod reads what it needs from your own copies. The first start takes about a minute while it reads R.E.P.O.
Builds on Riley Appleyard's Minecraft x TABS (MIT). BepInEx by the BepInEx team (LGPL-2.1). Unofficial fan mod: R.E.P.O. belongs to semiwork, Minecraft to Mojang/Microsoft and TABS to Landfall.
