Important info. A couple of glitches and things that popped up over the last few days.
1.) The 400RP/~40 seconds glitch.
I posted the video earlier, but you basically go by the military base and move back and forth creating/evading 4 star wanted levels. This is SUPER boring though. One of the dudes I showed the glitch to had an idea - get a school bus and put everyone in it. Whoever is going to generate the RP does it for everyone since being in the vehicle still gets you the RP. Not confirmed yet but if you are a passenger you shouldn't be tagged as idle by the server. This way cats can go to bed and let whoever is doing it rank up mad heads at once.
2.) The Survival Glitch (super important)
There is a glitch to get into the building on survival in the Railyards. You'll be invincible and the cops can't kill you. Do it solo for max RP and 30k.
However something weird happened last night.
I was doing the mission solo and a dude spectated it. He ended up spawning IN the mission on like Wave 6. He died, would go back to spectate and respawn in the next wave. That's one crazy glitch. The best thing tho? Anyone spectating gets the RP and cash. Basically just glitch the survival, let people in your party/crew know you're on level 10, and have them spectate. Easy 30k + ~2500 RP.
The real bonus
Get to Wave 10 and let the helicopter live. DO NOT SHOOT IT DOWN. Kill all of the cops. Then kill the shooter - NOT the pilot of the copter. Hop out of the glitch spot and collect everything. Waves 8+ spawn cops with miniguns and if you're lucky RPGs. These weapons carry over into Free Mode. This is how I was running around the map with 1500 ammo MGs and an RPG even though I haven't unlocked them. According to a crew member you can't buy ammo for them because you don't have them unlocked yet. Just go back to survival and reclaim them. The Railyard map might be the best mission in the game.
3.) More ez RP and Cash
Start the Blow Up 2 mission. Destroy the cars as Simeon wants. Instead of finishing the mission, drive around the corner (make a right) and you'll see the bank on the left. Run inside, up the hallway and across the veranda until you go through the doors. You can hold off the cops indefinitely solo. Do it for about 20 minutes (max mission rewards time) and you'll get ~20k cash and like 9k RP.
Shout out to the Coli members that helped figuring all of this out. They took our motorcycle hustle but we still gettin it
