!!! Fallout 2 Restoration Project required !!!

Kitsune:

Need charisma of at least 5, or CH 2 or more + speech higher than 80 % for her to join you. You only get one shot, if you fail she's gone for good. She is, well was a Chinese spy working for the Americans. If you ask her about her past you can eventually get her to teach you some of her skills. You gain +10% to your sneak, lockpick and steal skills.

Her main skill is lockpicking, and as long as her skill is better than yours, she will help you with it (like Vic with repair). As for combat skills, she's best with unarmed, melee, small guns and throwing - in that order. She can use all weapons, but she's rather bad with energy and big guns. She starts out with 80 HP and ends up with 130 HP and her AP will always be the 9 she starts with.

If you have left her out of your party and try to get her back while having CH 1, she will leave and disappear for good.

Cat Jules:

He used to be in the army, but was reassigned to guard duty at the EPA where he volunteered to some human/feline DNA experimentation. (He's basically a tribute to Cat, a character from the British Sci-Fi-comedy series "Red Dwarf".) If you ask he can give you some weapon training (+10% to small guns, Big Guns and Energy Weapons).

Notable skills; Small Guns, Energy Weapons, Unarmed, melee and on his final level a passable Big Guns skill. He can use all weapons, though he's not very good at throwing. He starts out with 80 HP and ends up with 130 HP, and his AP starts at 8 and ends at 10 on his last level.

Same as with Kitsune, if you ever have a CH of 1 when you try to recruit him or pick him up again, he will vanish from the game.

Dex:

A sociopathic killer and worse according to his files, innocent according to himself (He would say that wouldn't he?). If you play an evil character (negative karma) he will not pretend to be innocent. In fact, if you ask for his life's story, he'll tell you all about it. Good characters will never get to know, but maybe its better that way. He is easy to anger before you've recruited him, so pick your lines carefully or he'll go hostile. If you ask him if he can give you any tips, he'll teach you +15% speech and barter.

His main skill is speech, but unfortunately he cannot help you with that in any way. He's also good with Melee and Unarmed. Small guns are OK and Energy Weapons and throwing skill are passable on his last level. Unfortunately the weapons he can use are limited to unarmed, knives, pistols and sub-machine guns. He starts out with 80 HP and ends up with 130 HP, and his AP will stay the 8 he starts with until his last level, when it when it changes to 9.

*Female characters have the option to sleep with him before he is recruited. If you are good or neutral though (0 to positive karma), he will kill you afterward. So maybe not such a good idea.
