I may have found a glitch w/the APC patrol missions. Sometimes after destroying the escort cars, the lead APC becomes impossible to overtake, even when you use the rocket burst. The thing keeps speeding ahead, and you either stay at the same distance or fall behind. Idk if you're supposed to cut it off by taking a side route. I've had this happen twice now. Stupid part of this is that the Bmobile is essentialy a rocket on wheels while the APC, for some strange reason, has all the handling and speed of a Ferrari.

Anyone else have this happen?

I have gotten in situations where I couldn't catch up to the APC, but I don't believe it's a glitch. After you destroy the last escort, the APC becomes much more elusive, taking more blind turns down alleyways and the like, and yes, its handling properties and acceleration are pretty outlandish at this point. The means by which you catch up are basically the same as in any racing game... take the turns harder than the APC does. Cutting him off helps but it is also risky because the APC's path becomes so unpredictable at that point. Either way, even once you're in range it's very difficult to stay in missile range while still dodging the rockets, so I generally take at least half of them on the chin in order to get a shot off.

Not a great mechanic, especially because the firefly missions are just more of the same and there are so many APCs, but I'd be surprised if the APC is ever truly uncatchable, and if it is, it's an infrequent occurrence (I think I lost two of them over the course of the game, and I have completed that series of sidequests).

Yeh take the leader out first when hes slow unless you wanna race in tight alleys.
