I got to thinking when looking at the Mecha-Swarm; “Why not allow Terran to use Protoss weapons and armor and visa versa for Protoss?” Read me out!
What if Terran Marines got Protoss like armor and energy weapons?
What if Zealots got Terran like armor and metal blades?
So on and so forth.
What if Reigel (or someone else) was put in charge of a technology exchange program? They could take the fight to Amon using each others technology. What do you think?
