Vault Sentinel is a cyberpunk tower defense experience built around Crystal Guard — one deep arcade module with ten stages.
Deploy five tower types: Pulse, Prism, Nova, Laser, and Arc. Manually launch each wave, tap enemies for bonus damage, chain combos for extra gold, and aim meteor strikes on the battlefield. Frost, repair, and overdrive skills add tactical bursts mid-fight.
Enemies include runners, tanks, shielded units, splitters, flyers, and bosses across serpentine neon paths. Upgrade towers for damage, range, or fire rate between waves. Every run ends with a clear results screen — save records, export encrypted snapshots, and review performance charts.
Customize your operator profile, pick neon accent colors, and read the privacy policy inside the app. No account required; progress stays on your device.
