Tech Arena Returns!
Tech arena allows players to build vehicles (and pretty much anything they want to) from components and compete against friends, enemies and AI in an arena. These components and their functionality are each defined by scripts. On the front end, the player may create new components from existing types but these types are really templates of Lua scripts. If one so chooses, however, they can use the in-game code editor to write their own components from these templates or from scratch.
I've posted a new video testing out the new rocket launcher component and the physical effects of explosions in general. Fun stuff!
