Aegis Bastion: Tower Defense

Aegis Bastion is a portrait tower-defense survival game built around cool builds.

Construct prepared Turrets, acquire command Skills, and shape each sortie through level-up choices. Three-star upgrades branch into specialized paths, so the same loadout can develop differently from one run to the next.

BUILD YOUR COMMAND
- Choose from five active weapon sidegrades
- Prepare from ten Turrets and six command Skills
- Develop permanent Research across 35 projects
- Raise equipment Ranks and unlock new options
- Earn 36 Commendations and permanent rewards

CREATE YOUR BASTION
Customize themes, backgrounds, fortresses, effects, emblems, and music. Cosmetics change presentation only.

DESIGNED FOR REPEAT RUNS
Run Level and in-run choices reset, while Gold, Account Level, Research, equipment Rank, unlocks, Commendations, run records, and cosmetics persist. Experiment with damage types, status combinations, Auto Cast, and specialized upgrades as the waves accelerate.

How far can your Bastion hold?
