Game Types

Lambda comes with a few default gametypes but it also offers the ability to define a custom game type, this allows you to create your own campaign with the framework.

Structure

A game type typically describes a list of maps in which order the maps are played. There are also a bunch of tables where you can control many aspects such as invincible NPCs per name or class, round rules, enemy classes, etc.

Base	Base gametype (string)
