re: stapler
weird that only the clip appears
but in my experience Team Leaders are the ones who carry staplers and hardly anything else, so you should get it along with a Team Leader (whom you should not research, and should always sell, as he gives you good points for capture whilst unresearched).
Just completed my first Raider Arms Factory and im pleasantly surprised with how fun of a mission it was. Also the new addition of flame guards as an intermediate version of a firebat. It was a good challenge, im not so sure about the rewards or the points involved but its "okay" (to me any mission demanding a special vehicle and unique loadout better be worth it, looking at the save file the arms factory sticks around on the map a long time so at least there's plenty of time to organize a raid for it).
Rolled them with a Convoy of 13 gals and an Armoured Car (4x) RPG. Included were three gals in grav harness, three catgirls (one + the unipuma sisters), one gal in a heavy suit, and a human hero in defender armor (he killed 4 with a sniper rifle).
Loadout: Several Sniper Rifles, Two Harpoons/Stun, Two Zeerust Rifles, Two Light Cannons/AP, Heavy Laser, other assorted junk. Actually ended up doing some damage with hand cannons, didn't get much chance to do melee.
(strangely the Unipuma Peacekeeper armor with the shoulder rockets does Not have a Cat Claw or Gauntlet attack, which was a real surprise. That was the only melee confrontation and --blip-- no melee. The Sludger holding a gas grenade launcher was harpooned and then shot in the back a couple times with a handcannon instead.)
The Food Wars raid is underwhelming though, just some bandits and drifters to kill and it looks alot like a doomed farm but without the chaingunners.
