Evobot is a metamod plugin for the original Natural Selection mod for HL1. It provides AI players to fill out online listen or dedicated servers, or allow for single-player experiences entirely offline. It supports NS 3.2 and 3.3, and all gameplay features (including marines, aliens and the commander), across both regular and combat game modes.
