Loop kills
A loop kill is a bug killed by a flare, by a loop-only weapon, by a flare charm or union just after a flare that catches a bug, or by anything within a few seconds of a flare catching it. Loop kills give far more XP and score than weapon kills, and bigger loops pay more.
Recycling, but with more explosions.
