Prismhold

Prismhold is a tower defense game where every tower is a card. You build a deck from 196 towers across 14 elements, then draft from it each wave: a shop deals five cards, and you buy towers, spend gold to unlock slots beside the path, place them and defend against waves of creatures.

Build and evolve towers

Three identical towers merge into the next evolution, becoming stronger and bigger with a new look. There is no evolution cap, so you can keep merging through III, IV, V and beyond. Evolution III grants Mastery, which makes attacks faster and element effects more frequent; Evolution IV grants Legend, which makes attacks faster still and widens their area. A focused deck deals the same cards more often, helping you evolve faster.

Elements and creatures

The 14 elements are Fire, Water, Ice, Lightning, Darkness, Light, Poison, Nature, Earth, Air, Spirit, Cosmic, Laser and Firearms. Each tower attacks differently, with effects including dragon breath, chain lightning, black holes, falling stars, tornadoes and ricocheting diamond beams. Creatures resist some elements and are more vulnerable to others, so your deck needs a mix.

There are 200 creatures across 8 biomes, with tougher elite waves in every cycle. Every 10th wave brings a crowned boss with a shield, regeneration, fury or splitting. A boss that breaks through costs many lives, but gives extra gold when defeated. Flying waves can only be defeated by towers with the wing mark.

Game modes

In single-player, you climb a ladder of levels with no end. Each level takes place on the next map and is a little harder; clear wave 40 to win a level. There are 10 maps, and you can unlock slots with gold and fill the whole map, with no limit on the number of towers. In endless runs, spare gold can upgrade your towers for that run.

The Together mode lets two players defend one map with shared lives, while each has their own gold and towers. In Side by Side, up to 6 players each defend their own copy of the host's map. You can watch another player's map by clicking their card and try to outlast them. You can join an open game from the lobby list, or make a friends-only lobby and invite Steam friends.

Cards and challenges

Every reward is a card from an element you choose. You can upgrade cards up to ★10 and complete the collection. Augments change from run to run, affecting the economy, evolution and element mastery. The game also includes a daily challenge with the same map, deck and seed for everyone, Steam leaderboards, daily quests and 47 achievements. During your first two hours of play, you receive 13 gifts, each containing a card to open.
