The Expanded Sentries mod adds a new-ish class, the Defender, who uses Sentry damage weapons. These are traps and turrets that unlike minions, don’t follow the player. This is a playstyle that allows for the player to create deadly choke points without using tile based traps and effectively play tower defense style.
