Remote Sniper Drone (RSD-33) - (Digital) Done with Starcraft II in mind (hence the Raynor's Raiders logo).
This is an idea for a specialized sentry structure which can be programmed to a receiver that the user can use to remotely pick off foes from a safe distance from the battlefield. I'm sure the military already have these in real life.
There are some notes and ideas at the top, originally I wanted to make a structure that would act like a blockade similar to how the nullifier works for the Protoss but would be something for the Terrans, their defensive abilities are already overpowered enough.
This was done in PS with a round brush (blank canvas without any imports, although i did have a lot of fun with the lasso tool)
