Revenge of the Titans

Tower defense RTS where you build structures to stop waves of alien titans from reaching your base. The campaign spans 50 levels across five planets, each introducing different enemy types and terrain challenges. Between missions, you spend collected resources on permanent tech upgrades—new turret types, stronger barriers, or economic boosts that carry forward. Placement matters: turrets need power from nearby generators, and you'll rearrange your defenses as titan paths shift. The resource economy runs in real-time during battles, so you're constantly choosing between saving for heavy weapons or spamming cheap units to plug gaps. Procedurally generated maps mean level layouts change on replays. If you like tower defense that emphasizes adaptation over memorizing fixed solutions, this leans into that.
