## Summary

The Deadvelopment Center is, as its name implies, a center where you can upgrade each zombie and their abilities. You use skill points, which are gained by fulfilling tasks within a round, as a currency for upgrading. Unlike the Zombie Levelling System, skill points, levels and statistics gained will stay between rounds, even if you become a survivor between rounds.

Below is a list of each zombie and their upgrades. The Skull Champion, Swarmer, Elemental and Stalker do not have upgrades in the Deadvelopment Center.

This replaced the Zombie Levelling System in v1.4.5.

Note: All upgrades cost 1 point (except Digger Pickaxe which costs 6).

## Skill Points

You gain Skill Points by levelling up (3) or starting as a zombie during the round (10). Skill points save between rounds, so long you don't spawn as one of the initial zombies (which resets your points down to 10). Upgrades are also saved, so long you don't become a survivor.

## Levels

You can progress through levels by gaining Experience Points. This can be gotten by damaging a survivor with a basic claw attack (1), damaging a survivor with a basic claw (1) or damaging someone as a Brute (1).

There appears to be an infinite amount of levels. The graph below show how much Experience points is required to level up to 10, though the game can go past that. Levelling up shows a clear pattern of 5+3+4+5+6+7+..., respective to the rank.

• To level up, you require the following amount of Experience Points:
$Experience Required = 5 + (3+4+5+6+7+...)$where the highest number added is$Next Rank +1$ where$Next Rank ≥ 2$
• For each level you get the following amount of EXP (for Ranks):
$EXP Earned = (New Level × 10) + 5$
Level Experience Needed
Level Zero 0 Experience
Level One 5 Experience (5 total)
Level Two 8 Experience (13 total)
Level Three 12 Experience (25 total)
Level Four 17 Experience (38 total)
Level Five 23 Experience (61 total)
Level Six 30 Experience (91 total)
Level Seven 38 Experience (129 total)
Level Eight 47 Experience (176 total)
Level Nine 57 Experience (233 total)
Level Ten 68 Experience (301 total)

## Tips

• If you feel as though your skills with a certain zombie are lacking, grind up some skill points and upgrade.
• Press "C" to enable the menu when you are a zombie.
• Any upgrades won't affect Rapid Infection, though you can still get skill points from it.
