You get a lot of extra points for kill streaks, and you lose points when you die. So you're highly incentivized to get kills as the monster, because you want to offset the points you lose by dying, and your kill streak still continues between human and monster state. I think it's a really fun system because it makes you feel like a big payout is always within reach, and it's really satisfying when you get lucky with the virus vials and get a big kill streak with a high level monster.
