Leaper is by far the best to upgrade. You can have 300 Hp, A C4 that deals 50 damage to survivors, and go super high in the air with flight. This takes alot ot points but it is not that hard if you start zombie (you get 10 points.)
Leaper is the best upgrade for most fun. Brute wins best upgrade when it comes to killing/damaging survivors more easly with upgrades.
What do you think?
