Regular Wasp: I use it early at the start of Warzone Matches to take out lots of people and get the jump on weak bosses and vehicles. It proves to be useful for preventing enemies from coming into Fortresses, Monuments, and Spires.
Oni Wasp: I mainly use this Wasp in Firefight since I can survive the whole match with one, but I like targeting air vehicles with it since 10x better against air vehicles than the normal wasp.
Hannibal Wasp: I use this Wasp strictly for clearing out armories, destroying ground vehicles, and especially demolishing Infantry and Spartans. I try to stay away from air vehicles since the experimental bombs are hard to hit air targets with, but they do a great deal of damage if they hit so most times I’ll risk it.
How do YOU use the three wasp variants?
