I've been working my way through the unlockables, and so far I only have about 15-20 of em. Most of them are obvious on what they do, but the question I have has to do with the unlockables such as helium, paper mode, bignoggin, etc. Ive looked all through the net and the manual, but what exactly do these unlockables do and how do you use them? So far Ive gotten the helium one, but how do I use it? Im thinkin the bignoggin one has to do with their heads. Can anyonel help me out with what some of these other unlockable do? thanks heres a list I found of the ones Im trying to figure out: 46. Chicken Mode Cheat : Complete M06 Castle in Firefight on Elite using only one Rifleman with the M15/M203 kit. 47. Slow Mo Mode : Complete M07 River in Recon on Elite using only one Rifleman with M16/M203 kit. 48. MegaNoggin Cheat : Complete M01 Caves in Firefight on Elite, using only one demolitions expert with the M4 and M136 kit. 49. Paper Mode Cheat : Complete M15 Red Square in Recon on Elite using only a sniper with the M24 and frags kit. 50. Helium Mode Cheat : Complete M13 Airbase in Firefight on Elite with a full team, and not losing a soldier.
