This would've been 2014, I played in a 100 v 100 paintball game in Western Massachusetts. It was February, so the snow was pretty deep. At one point I stepped through some ice up to my knee.

Rather than run straight up elimination, teams accrued points by holding positions at certain times. You've got the bunker at noon? That's a point. 12:05? Nothing. This led to us desperately defending objectives against 6-to-1 odds waiting for the ref to announce that we'd scored the point.

Thats sounds like the type of fun I'd be at! Long term objectives in a short term game

This reminded me of a game of capture the flag I played also in deep New England snow, with just a few friends, but over maybe a half-mile schoolyard with various buildings and playing fields.

Long periods of silence and slow creeping punctuated by moments of sprinting when you were spotted. Some of the most fun I ever had.
