Vortex Siege

Vortex Siege combines collectible card games with roguelikes, procedurally generated upgrades, base building, and optional co-op for a unique deckbuilding experience.

Defend Your Town Against Invaders

Defend your town against five distinct invading realms in a desperate battle for the future of your world. By closing all of the portals, defeating each of five bosses, and sealing the path to each realm, you alone can drive back the invaders.

Collectible Card Game Battles

Fight battles against the invaders with minions, items, actions, and trigger cards drawn from a deck that evolves over each run.

• Use combos, removal, and board wipes to gain and keep control of the board

• Build your deck by stealing cards from the decks of your opponents after each match

• Start each match with 1 energy per turn and gain more maximum energy each turn, allowing you to play more powerful cards as the match progresses

• Choose your enemies carefully, both to avoid your weaknesses and for the faction-specific cards you can steal from them to ensure future victories

Highly Customizable Cards

Modify cards in exciting and unique ways! Make the cards your own and create combos and abilities we never dreamed of. And yes, break the game.

• Add rules to cards with unique combinations of trigger, on play, and constant effects

• Remove flaws from cards that have shortcomings or are tricky to use

• Reduce the cost of your cards to make super-efficient high value cards

• Upgrade costs adjust dynamically based on the game's card rating algorithm

• Over 150 base cards with many more planned, but the cards you end up with will be unique to each run

Base Building

Build up your town to shore up your defenses, generate economic advantage, and create buildings that let you improve your deck.

• Use turn-based tower defense style strategy and build walls, barracks, and mage towers to fend off the enemies until you manage to close the portals in an area

• Create economic resources that can be used to build new structures or improve your deck

• Improve your deck by building shops, alchemy labs, keeps, voidgates, and chaos portals

• Use the tech tree to unlock new buildings and upgrades

Roguelike Deckbuilder

Survive through battles and waves of enemies while tweaking and improving your deck.

• The enemy starts with full health every match, but you get worn down over time, making defensive strategies key to long-term victory

• Start with a deck of weak Starter cards and work your way up to powerful Transcendent cards

Co-op Mode

Team up with your friends to play simultaneous co-operative matches against the invaders.

• Turns are taken simultaneously, and players have their own decks, hands, and cards on the board

• Players face a single enemy at a time, scaled up to match the power level of multiple players

• Make joint decisions about strategy, assisting one another, choosing which enemies to fight, and more
