A kamikaze trick: when throwing grenades, to get the most possible damage out of it, try to throw it straight down so aliens won't hear the dropping noise. then taunt or reload so aliens think they have a shot at you. They'll get real close and... !!!!:Grenade:!!!!
NOTE: This is frowned upon by superior players so only do it with an unnamedplayertag
Frowned upon by superior players?
That sounds like just the thing to kick them down a notch.
