Geyser Trap will be your best friend while doing this!
You see a hacked vending machine and afraid to go up to it?
You won't any more!
[1st]
Place a geyser trap on the clowns face, of the hacked vending machine.
[2nd]
Yes, this sounds crazy, but run directly to your geyser trap!
[3rd]
If done correctly, the geyser trap will push you back with no damage done to you and the bomb will come out, but you'll be a safe distance when it goes off!
I haven't been killed by a Vending machine since!
*NOTICE*
Be careful while doing this in small places because you might not have enough room to do it safely!
I'll be posting youtube videos soon, off all of the tricks that can be done in BioShock 2s multiplayer!
