Sentry System

Sentry System combines roguelike systems with classic tower defense. You collect and modify sentries, shape enemy routes with mazes and use interactive environments to defeat varied enemies and bosses.

Build your sentry roster

Choose from a wide selection of sentries, then change their damage types, add status effects and improve their stats. Combine effects to create builds such as explosions that trigger explosions, chains of stunning lightning and powerful damage-over-time effects. Strong effects can come with significant drawbacks, so you weigh the risks against their potential payoffs. Different sentries and status effects counter different enemies, making your choices important.

Control the battlefield

Build mazes to direct enemies along winding routes, past explosive devices and into choke points. Position sentries to maximize their damage, and use environmental features to gain an advantage. You can charge explosive devices with sentries, power amplifying antennas with generators, move map tiles and use other environmental mechanics.

Face enemies and bosses

Enemies have varied abilities: some shield others, accelerate, teleport or explode when defeated. Different threats call for different counters, so you choose your sentries and status effects carefully. Boss encounters take place on a larger scale and test your use of both sentries and environmental mechanics; each boss presents a puzzle that rewards skill and strategy.

Progress through routes

Advance through a randomized network and choose routes that lead to items you need. You can trade some resources for others, and must manage your resources between battles while making the best of randomized choices. A varied roster of sentries helps you handle the challenges ahead.
