Streaks in this game are easy. There are 2 things that ruin rampants. 1 is time and the 2nd one is one shot killing guns like the t-bolt and rpg. Don't camp if your close to a rampant or you will go paranoid and die of something stupid. Play it like its normal. And kill every noob that has a sniper. If you don't you will die going 19-1 from a level 14 noob camping in the corner that headshot you.
Camping is normal for me, I'm a defensive person
