You want a reason, how about four? They're called bodyguards, and every one of them is packing. Me, too - so baby makes five. Add to that every Chairman in this joint is armed, and not with some hold-out peashooter like maybe you smuggled through security.

Benny's bodyguards are lame. They wear fedoras and carry peashooters. The Chairman head honcho -- the crafty cat angling to make the whole Strip his -- ought to have better protection if he's going to be scheming under everyone else's noses.

So I gave Benny's bodyguards some new armor to wear -- the Casino Security Armor. It uses flamenx01's Shabby Suit mesh as a base, with a new texture and a security vest thrown on under the jacket. It's pretty flimsy but it's light and can be repaired with leather armor. 7 DT, 7 pounds, 70 health. Ring-a-ding, baby!

The bodyguards also now carry 10mm SMGs and Sawed-Off Shotguns instead of their silenced 22s. In addition, I gave them minor facelifts, removed their dumb hats, and gave them mustaches. I think the mustaches make them look less baby-faced. I know the rest of the Chairmen are clean-shaven but these guys are Benny's guys first and foremost, so this serves to distinguish them from the rest of the tribe and mark them as a separate clique with closer ties to the boss.

If you let Benny send you to the Presidential Suite to get you whacked, his bodyguards will come in using silenced 22 SMGs again, and they'll also be wearing new masks with assets from AusAllerWelt and kvatchcount's Powder Ganger Balaclava. It's implemented as the Hatchetman's Hood and can be repaired with the base game's headwrap. It doesn't offer much of anything but a +5 crit chance. Both the hood and the armor can be found on the bar in the Presidential Suite so they can both be obtained even if you work around killing the guards.

Notes: The guards are still two sets of twins. It would've been way more trouble than it's worth to change that. I feel that removing their hats and giving them two different sets of guns does enough to make them look less like clones of each other. Also, one of these guys was a real pain in the ass and I couldn't get him to equip the armor in his inventory, so there's a startup quest with a script to brute force it.
