Level

The character starts at Level 1 an can raise it by obtaining Experience. Experience is granted for nearly any action in the game: killing Zombies, crafting items, searching objects and dead zombies, chopping down trees, fulfilling Tasks.

Leveling up grants one Skill point which can be redeemed at any time later in the game.

The requirements for the next level increase exponentially. Therefore leveling up might feel quite fast at the start (several levels per full Energy), but will slow down soon to a crawl. The formula for required Experience to level up from a level is as follows (rounded to the nearest integer):

$Round(49.5261 * 1.155 ^ {Lvl-1})$

The formula for total amount of Experience required to reach a specific level is roughly (slight deviations are in order due to rounding):

$49.5261 * \frac{1-1.155^{Lvl-1}}{1-1.155}$
