Doomsday

Doomsday is a single-player card-based roguelike in which you play a scientist seeking world domination with a giant laser cannon mounted on a spider-legged robot. Across 15 levels, you take on opponents ranging from teenage bullies and military commandos to forest witches and Kongclops. You assemble a doomsday device from components and artifacts, building a weapon powerful enough to overcome each enemy.

Build your device

Each level gives you seven turns to play cards and score enough points to defeat the enemy. Component cards add pieces to your weapon, while action cards can strengthen those pieces. Enemies have unique effects that can disrupt your plans, so you work with the cards and artifacts in your deck to find useful synergies and exploit their weaknesses.

Between levels, you can add or remove cards, obtain artifacts or explore on a side quest. You can choose from over 150 cards and 100 artifacts, with more cards and artifacts unlocking as you play, including some with rare, game-breaking abilities. Runs use different combinations of cards and artifacts.

Levels and challenges

The game has 15 levels and a dozen enemies. More than 50 exploration events offer uncommon rewards. There are three difficulty levels and a tutorial mode that teaches the rules; each round takes a minute or two. You can also check your high scores on the stats screen.

The game features original art by Flynn Nicholls and an original soundtrack by Dylan Walker and Josh Richmond.
