Before we start giving this game out to a few people, I want to get a classic sandbox gamemode working.
I started with implementing the basic tools and entities. Physgun, solid welds, thrusters and balloons. We want to rethink tools and see how they can be done better but for now I decided to stick with what we know so we can make sure it all works in multiplayer.
Unreal by default is missing a few things for a multiplayer physics sandbox, luckily I can add support for everything without forking the engine.
