Problems getting I can't believe that worked

[Lifestalker]

How do you get this achievement? I've tried doing a ton of backflips on a trampolin and everything, can anyone tell me how it can be done?

[reconrey]

I can't get it to work either. It may be bugged.

[Nosferatuno]

I believe it's bugged. I had exactly 10 flips in my combo (not flips completed) 4 front, 4 back, 2 180 front flips, and it still did not grant it.

[Mochilla]

Probably bugged, I tested it a bunch of ways, none worked

[Duchess of Soles]

This and the Trampoline(sp) one seems bugged, I've done 50000000 front flips, as well as -exactly- 10. Neither of which gave me the achievement; same with bouncing 'once' on all 5 trampo's without hitting the ground.

[Ridiculisk]

I got it by going to the anti-gravity testing facility and floating around in the fan room and continously flipping and by the time I reached the ground again, I got the achievement. I couldn't get enough flips in jumping on a trampoline, so I thought of going to the anti-grav chamber and it worked first time.

I have the trampoline achievement. Took some work, but I managed it.

To achieve the trampoline achievement simply start on the trampoline by those protesters, make sure you hop onto the edge first so it doesn't bounce as you need your first bounce to be in ragdoll mode. then simply bounce towards the construction site (obviously bouncing on the 2 in the pool) and once you bounce on the one in the construction site immediately maneuver towards the fans on top of the building in the construction site so that it gives you a boost. Then its pretty much home sailing from then on as all you need to do is make sure you land on the last trampoline at the spawn point and you should get the achievement.

[FangsFirst]

Oh, I started from the construction site. That made it easy, except the first time I completely overshot the one near the goat tower.

[SpicyFemme]

The easiest way is in the anti-gravity chamber. Just hold RMB and back.

Well somehow i glitched with the help of the blue car in the tunnel and got the achievement, even i didn't do the recommended thing (jumping on the trampoline)
