I know that:
Radioactive- makes you lose health for a long while
Stealth- makes your position invisible (even when you are standing up) for a while
BOMB- Kills you when picked up
Invulnerable- Drains your health, but keeps you alive for a while
THE GOLDEN GUN- Simply a gun made of gold that kills with one shot (5 shots)
Upgrades Multiplier- Gives you 5 extra game play credits [regainable]
Anyone know what the rest are?
And any ones I missed...
