Versus Survival, Upcoming Zombie Apocalypse, Guns! How many?
The first Survivor team sets the time. The second team tries to beat it. Then the first team tries to beat the second team's time. Then the second team tries to beat the first team's time. And then the... you get the idea. Rounds keep switching until someone fails to beat the previous time.
This is a great way to try Versus. Rounds are only as long as you can keep beating each other’s times. There are no rushing Survivors. Infected spawns get quicker as the time increases. It is mayhem filled with all the weapon perks and items. What’s not to like? Give it a try.
