In Prototype, challenges that required you to accumulate X kills within a certain timeframe rewarded multiple kills for tougher targets (for instance, killing a tank would increase your kill count by 10).
One of the very first Radnet challenges in Prototype 2 would have you kill 30 targets with a grenade launcher within 30 seconds. Seeing how I have an obsessive compulsive disorder with challenges, I am really aiming to get this done, but have yet to find a sufficiently large mass of targets with which to accomplish this feat. However, if vehicles do count as more kills, I might be able to get this done.
So do the mechanics from Prototype carry over, or do I need to simply wait until I find a mass of targets on which to unleash explosive fury?
