Solitary Sentinel

Solitary Sentinel is a single-player roguelite in which you defend against waves of evolving enemies. You command one Sentinel, upgrading it as you progress and adapting your tactics to survive. Its minimalist visuals and straightforward controls frame gameplay that combines elements of Space Invaders and Missile Command.

Control your Sentinel

You can aim manually or activate Auto Aim, which lets the Sentinel target enemies automatically. With Auto Aim on, you can also select targets yourself. As waves pass, enemies develop different evolutionary traits, so each run calls for different strategies.

Weapons and upgrades

Customize the Sentinel’s abilities and strengths with upgrades, and combine mechanics to build synergies. Your arsenal includes lasers, Tesla coils, black hole generators and meteor callers, giving you different weapon combinations to try against the changing threats.

Waves and difficulty

The challenge increases with each wave as enemies become more formidable. Surviving more waves unlocks new difficulty levels for future runs; higher difficulties unlock more powerful perks that improve the Sentinel’s abilities. You can also augment individual waves to make them much harder in exchange for more rewarding loot if you clear them.
