Sentries

Sentries are powerful and special entities that usually have strong turrets on top of their base. Most sentries are based around lesser Crashers and Bosses. Some are able to generate bosses after they are killed. Sentries usually spawn in the Pentagon Nest or around Sanctuaries.

These Sentries are Non-Spawnable due to being deleted, unbalanced or are not meant to be spawnable. However, some of them can be accessable by going to the Sentries page of the Event Developer Gallery here
