Cosmic Dust & Rust is a space-set tower defence game built around a shift between preparation and direct combat. Its first stage, ship management, puts the player in charge of improving the vessel from within, including building and upgrading turrets and defensive systems. Side missions offer another activity alongside that maintenance and construction.
The second stage changes the player’s role: rather than managing the ship, they manually control it, its main cannon and its super-weapon defence systems in an action sequence. That contrast gives the game a distinct rhythm, moving from tactical investment in the ship to hands-on fighting. Combat features varied enemy types with destructible parts, while secondary missions can award aluminium and gold, tying optional objectives to ship development.
The stated design also mixes strategy and action: players build up defences, pursue side objectives and then take control of the vessel against enemy forces.
