Viper

1. Keep jump pressed until you hear a beep. When you hear the beep, press alternate fire/enter.
2. I think the viper wasn't that close after all.
3. Don't think so, never had any problem with that.

1. Hold secondary fire, aim at a target, and release after you hear a beep.
2. Dark walker secondary is not very useful against vehicles.
3. Viper does not "crouch." It is low enough to the ground to be able to just run over them.

I have a few questions about the viper.

1: How do I do the seld destruct? I always do it and it says it isn't ready or something.
2: When i use the Dark walkers alt fire and there is a viper near by the viper seems to be unefacted. why?
3: Is there a way to crouch (like the manta) to bring it back to the ground and make it easier to get road kills with it?
