I got blasted (boom headshot) by a clearsoft (not even painted), manuallly cocked P90 that felt like it was shooting 10fps.
The dude was hunkered down behind some scrub. I put a couple of shots on him...then a burst...then another burst...then the rest of the mag...then I changed mags (must have missed him with the first 120rnds

) and rushed him, firing on the go.
About 15ft away I felt this tiny "thwap" on my hat...that didn't sound like a twig...so I stopped, called my self out and went back to respawn. It felt like a 2 year old threw a tic-tac at me...LOL
My teammate blasted the guy...then laughed his ass off the next time he saw me.
