I was playing online yesterday (PS3), and I'm convinced two guys have managed to do slight modifications and hack the game somehow?
Now, unless I'm wrong, the Liberator is not a vehicle that can be customized right? Well, I was in passive mode or whatever you call it, and two guys where roaring around in Liberators... one looked normal, the other had a slightly different shape to the body, and it was all chrome, that mirror paint job look. Someone else showed up on the scene as these guys where trying to take me down, even tho you can't, however, one seemed to be able to see me, and did shoot at me and hit me, like I was visible and not in spectate mode(?)... I ran and jumped behind something, then he focused on the other guy in the area... I stood on a brick wall and the guy in the chrome shine truck slammed into it, hoping I was there... then he parked the truck, got out and ran over to the other guy where his friend was to pull the guy out of the car and shoot him... which he did. But I took the opportunity to steal his truck. I was in the Hollywood area thing near Michael's house, and managed to steal the truck and get it all the way to the air port.... then I see the guys username appear in the truck... and he took control of the truck... I was still in it, then for some reason he jumped out and I got control again... I figured I would go and drown his truck in the ocean if he can manage to do that... but then as I hit the sand, he was back in the truck again somehow, and took control.... I guess he knew what I was thinking, because suddenly the truck stops, and my character gets out, and starts casually walking towards the ocean... I had no control at all. Somehow he was controlling me! I wasn't about to give him the pleasure of making me kill myself with him at the control, so I quit the game on him.
Also, another thing... while those two where driving around killing anyone who came near them, one of them was shooting at me from in the liberator... only not with machine guns, with rockets!
And also again, the liberator is a shape like a cabin truck... this other guy using the shiny chrome one, the shape of the truck resembled the same look as an actual popular monster truck named Grave Digger. Kind of an old 50's shape, only in the game it was all chrome like I said.
As for the other guy in the regular looking Liberator, he was driving up and down the cliff-side like it was nothing. It was like he had no boundaries on traction, depth and what not. He just sped up the side of the cliff, sat there and waited for people to come by, then sped down and attacked them with the other guy. And when I say sped up the cliff side where theres usually no traction, I mean he was up the top within 2 second, with the truck not even hesitating to get up there. He did this constantly, not just once or twice.
