Synthmaker

Simple SWEP for the purpose of spawning the crabsynth NPC.

It seems VALVe never finished this NPC - it has no AI, and is not even solid. If you step into its head you can see there is a minigun type weapon inside. It is only seen briefly near the end of the singleplayer game.

Primary Fire = Spawn a synth where you are standing in the direction you are facing Secondary Fire = Remove ALL spawned synths
