This plugin increases the number of AI monsters active at any one time. The increased number was the default setting in Aleph One until 1.1, when the Marathon 2/Infinity defaults were restored.

You should use this plugin with scenarios built specifically for Aleph One, such as Eternal X, Kill Them All, or Phoenix. When/if those scenarios are updated, you will no longer need this plugin. Do not enable the plugin for scenarios orginally designed for Marathon Infinity, such as Tempus Irae.
