In Dead Space 3 We Finally get to design our own weapons from scratch at a Weapons Bench so everyone can create their necromorph killing machine. For example a line gun with a ripper as secondary fire or a pulse rifle that sets necromorphs on fire, just about anything can be created: if you dream it you can build it.
My Weapon idea, a launcher that shoots detonator mines and secondary fires line gun mines with a attachment that protects users from mine explosions.
-allows you to shoot in shoot in 'X' or '+' alignment, can pierce through 2-3 enemies. More powerful than a fully upgraded PC, but consumes two rounds per shot and firing speed will be one level slower.
Plasma Cutter + Force Gun = Force Cutter
-Primary is PC, Secondary is FG, Precision weapon with crowd control. PC remains the same, but blast radius of the FG is reduced a bit.
Ripper + Flamethrower = Flame Ripper
-Primary is Ripper. Secondary fire super-heats the circular blade for heavy damage, blade duration is reduced by 50%.
Contact Beam + Rivet Gun = Claymore Gun
-Primary fire is an extra large, wide-range shot using multiple rivets. No charge needed, holds twice the rounds of a fully upgraded CB, but CB damage is reduced by 50%.
-Secondary fire is an omni-directional blast of rivets that deals heavy damage.Uses four rounds per shot.
Shotgun loaded with stasis plus a sprayer that ejects liquid nitrogen that freezes necromophs dead in their tracks. Using the Sprayer known as the Cryo Torch to freeze then use the shotgun or bash them to finish them off is a way to kill the necromorphs; I named it the Cryo Blaster.
