I've found tons of videos showing the under water money exploit, but none giving detailed info about the weapons that can be found for free at these sites. I'd like for this to be a place for people to post detailed info regarding this stuff because I think, although I'm uncertain, that you can find all the game's weapons for free at one place or another. I'll start with some of the stuff I know for sure, and anybody else can follow a similar format, or be even more detailed if possible.
LOCATION: To the right of the train trestle connecting Elysian Island/Chum St. & Banning. The $7,500 briefcase is here.
DESCRIPTION: Shallow, small boat of some kind
WEAPONS FOUND: Grenades on the sea floor at the top of the boat, Sticky Bombs in-between the last and second to last cement barriers holding up the trestle, Pump Shotgun beside the boat on that same side, regular Pistol on the same side just above the shotgun, SMG on the foot of the boat and Health/Armour on the sea floor on the bottom side opposite the other guns. There's also a crowbar on the top of the boat above the briefcase.
LOCATION: ~ 2 inches up on the map from the Del Perro Boardwalk/Right below the Tennis Court below Pacific Bluffs
DESCRIPTION: Not sure what it is, some kind of old oil facility? The $25,000 briefcase is here
WEAPONS FOUND: Assault rifle on the cement base of the pillar holding up the big/empty tank on the left side facing away from the beach, RPG on the edge of the hill right above that, MG below/to the right of the assault rifle on the cement base (this one's larger, supporting several pillars instead of just one), Grenade Launcher on the sea floor on the right side of the big/empty tank, Armour on the top right (if facing away from the beach) of the entire structure (if swimming from the beach, I mean when you first get there) on the sea floor - close to the grenade launcher, Health on the tank its self right above the assault rifle.
Hopefully this thread works out and people give enough of a crap to post detailed info, and hopefully my stuff here is easy enough to understand. I'd like to find the AP/Combat Pistols and the Advanced Rifle somewhere. I wonder if they exist outside of obtaining them in missions/Ammunation?
Anyway, thanks in advance!
