These Doomed Isles is a strategy indie simulation game that blends city building with roguelike deckbuilding on PC. Players take on the role of a god who raises land from the sea, constructs settlements, and defends followers from waves of invaders using a deck of cards harvested during each run.
Gameplay
The core loop centers on expanding an island chain while managing a deck of cards. Each run begins with limited resources and a basic settlement. Cards allow players to create new land, construct buildings such as farms and fortifications, and summon effects to counter threats. Harvesting new cards each cycle lets players refine their deck for better survival odds and stronger synergies among the more than 300 available options.
Defense forms a major part of progression. Invaders arrive in escalating waves, and powerful bosses appear later. Cards provide direct attacks like meteors or storms, along with status effects that weaken enemies over time. God powers unique to each of the four civilizations add further options for turning the tide. Relics and curses introduce run-specific modifiers that alter resource gathering, combat, or building efficiency.
Failure teaches through roguelike elements. When a settlement falls, players carry forward knowledge of effective card combinations and building orders. Ascension levels, up to 15 in total, increase difficulty while rewarding refined strategies. The pixel art style and soundtrack support the theme of isolated, threatened islands without overwhelming the strategic focus.
Game Modes
These Doomed Isles centers on singleplayer run-based sessions where the goal is to complete follower prayers and achieve victory before invaders overrun the islands. Each attempt features procedural elements through card draws, enemy compositions, and relic or curse selections that ensure no two runs play identically.
Ascension levels serve as the primary progression system, scaling challenge across 15 tiers for players seeking repeated attempts with greater stakes. Friend leaderboards provide a competitive layer, allowing comparison of scores from completed runs without altering the core singleplayer experience.
No separate multiplayer modes or seasonal events appear in the current version. The structure emphasizes repeated runs with deck management and long-term planning over one-off matches or co-op scenarios.
Gods and Civilizations
Four distinct gods launch with the game, each tied to a civilization that changes core mechanics. One follows a Celtic-inspired approach focused on natural growth. Another incorporates Greek elements such as housing upgrades, taxation, and festivals. A third draws from Mayan themes with temples and ritual mechanics. The fourth completes the set with its own aesthetic and ability suite. These differences affect card pools, building options, and god powers, encouraging players to experiment across multiple runs.
Over 20 enemy types and 12 bosses test these varied playstyles. Enemies range from basic raiders to specialized units that exploit particular weaknesses in settlements or decks. Boss encounters demand precise timing and synergy use to overcome.
Is It Worth Playing?
These Doomed Isles suits players who enjoy strategic city builders combined with roguelike deck management and high replayability through card synergies and ascension challenges. The mixed reception on Steam, sitting near 67 percent positive from roughly 175 reviews, reflects appreciation for the unique blend alongside notes on pacing and depth that vary by individual preference.
The game reached full release in late 2024 after Early Access. Post-launch support has focused on bug fixes rather than new content. Those drawn to efficient puzzle-like runs, god-specific strategies, and competitive leaderboards will find the most consistent engagement. Players seeking ongoing updates or broader multiplayer features may want to review recent player feedback before purchasing.
