Jsrnjmc: If i were you id just pass up zero's missions for right now, if its that much trouble. For some reason his missions are particularly hard, but pass him over for now and you can continue doing all of the other missions.
reddewdrinker2: Theres no real secret to the 2 minute race, just drive quickly but only when you can do it without hitting something, technique is everything.
Gamer05: I take it you mean Vertical Bird. heres a technique for ya. if you have any of those sachet packs or w/e their called(remote explosives) then once you get to the hydras then plant a sachet pack on each of the other hydras ON THE SIDE FARTHEST FROM YOUR HYDRA(the one not below deck). Then, go stand near your hydra, detonate the charges then climb in. this way you have as few as one hydra following you and if you fly just above the surface of the water the hydra has a good chance of crashing.
j-jay: youll need to get your pilot license(flight school, you get from your own airstrip in Toreno missions).
