I cannot get Sulik to accept any other weapon than the damn combat knife. I know this is a bug as I've seen it mentioned elsewhere but I cannot figure out how to get past this and it really makes things frustrating. I've removed all other weapons, changed preferences, told him to remove weapons. Everything but remove everything he has, which would be a chore cause he holds a lot. Please HELP

Sulik haven't all animations so he's limited to what he can use. From Fallout Wiki:
[i]Weapons and their animation frames
Team members can only use weapons they have the animation frames as Sulik cannot throw grenades, although he has points in the skill. He cannot throw knives, as the throwing animation is separate to the Swing and Thrust knife animations. The .223 pistol is one of a handful of weapons whose animation does not fit their weapon type; it uses the SMG animation, and Sulik can use it even though it is a pistol.
A spear or knife at the start gives him an extra attack more per round than his starting sledgehammer weapon. Although burst weapons are of course always hazardous, Sulik will put the 10mm and subsequent SMGs to good use; he is valuable as a ranged weapon character. He can use any of the top tier melee weapons, and SMGs such as the HK P90c, 10mm ammo, and H&K G11E, caseless ammo[/i].
What weapons are you trying to equip him with?

I wouldn't recommend giving him a H&K G11E EVER unless you just want him spraying valuable rare ammo everywhere and/or killing you. Stick with a Sharpened Spear, Combat Knife or Spiked Knuckles (which you can get in Klamath from the Dunton brothers) until you can get a Mega Power Fist or Super Sledge. If you're dead set on him having a ranged weapon, go with the .223 pistol. It doesn't have burst fire and the ammo is common and cheap.

Ummm, I'm talking ANY weapon. He won't take knuckles, the .223, the powerfist, nothing. Believe me I've searched before asking.

Additionally, I cannot fuel my car. I tried clicking on the engine block (just enters the car), I've tried equipping the MFC, can't figure it out.

I'm starting to wonder...best game ever or buggiest game ever?

Well I finally got the car to recharge...but damn, they didn't make it easy...

You're not playing without patches, are you? Fallout 2 v1.0 has MANY bugs. I'm not exaggerating. If it's your first time playing, I recommend you install killap's unnoficial patch (official patches already included), otherwise, install restoration project, which add things that the devs hadn't enough time to add (like the submarine).

If your game is patched already, and you're having problems with sulik, send me the save so I can give it a look.

I think its time for you to install the unofficial patches and start another playthrough.

They're a must for Fallout 2.
