I was thiking about a new piece of equipment as seen in Aliens (Alien II), it is the vest/arm that is used to "brace" the machine guns (heavy stubbers).
This vest sprouts an arm which can support some of the heavier weapons, this vest is often used by Guardsman Storm Troopers and Arbites who need heavy support.
Allow the firing of Heavy Weapons up till 45kg without the need to brace, though does give the wearer a -10 to all dodge rolls due it hinderance.
Armageddon Patter Assault Stubber
Class: SP Heavy
This incredibly sollid heavy stubber is the big brother of the Armageddon Pattern Autogun, it fires large cal. slugs which are stored in a heavy banana magazine which inserted in the side of the gun.
ps. I don't really like the name, anybody a better idead
pps. Yes I know it by passes Bulging Biceps
The Mars Pattern Lancer
This ancient weapon is perhaps still one of the best assault weapons up to date.
It combines a heavy autogun with a fixed chain bayonet. The only problems are due to its lack of a stock the range is a bit limited and that due to the larger calibre it has two smaller clips instead of one larger
Special: Tearing, Unbalanced
Special: Revving the Chainsaw gives a +10 bonus to the Intimidate Skill.
Made this weapon by combining a modified Autogun and a Chainblade
