It's a challenge.
Objective: Build a starter cruiser for actual game (beta or 0.13.2113 more)
Result: I build a cruiser with nano and smg, why?
Answer: It is to learn that to play medic can serve, that is besides the reason why the robot resembles an ambulance.
I tried to do it in FreeJam style when it was built and I think I succeeded. ^^
