Outbreak point system for killing zombies
The 5 perks cost 75,000 points in total, perks at max level are still far weaker than their counterparts in CW (with the Sprint speed of Stamin up being the outlier). Best example is max level jug in Vanguard giving you the same amount of health that base tier jug does in CW
Covenant system is just perk and skill tree tiers from CW ported into a shitty rng system where you can only have 3 at a time
