Minecraft creative mode and Portal's portal gun in GTA V's Los Santos. Build, blow it up, then portal through it.
You play in GTA V Story Mode (solo), and two other games join you in Los Santos.
Minecraft creative mode, for real. Real Minecraft runs on your own account next to GTA, and it is drawn right into GTA's world.
Press Tab for Portal's portal gun. The Minecraft HUD swaps out for Aperture Science's portal gun.
Press Tab again to go back to building.
You need: GTA V Legacy (Steam, Story Mode), Minecraft: Java Edition and Portal. Melty sets up Minecraft and starts both games for you. Pick Story Mode on GTA's start screen. Nothing from any of the three games is included: each one is read from your own copy.
Story Mode only. The mod never goes into GTA Online.
Credits: built on Melty's Minecraft x GTA V passthrough (MIT), with ReShade by crosire, Prism Launcher, Eclipse Temurin, Fabric API and Java-WebSocket. GTA V belongs to Rockstar Games, Minecraft to Mojang Studios and Portal to Valve. This is a fan mashup.
