Xenocrystal TD

Xenocrystal TD is a tower defense game in which you protect Xenocrystals across the alien worlds of the Vorrak. You spend energy to teleport towers into place and use orbital abilities to attack aliens directly or support your defenses.

Towers and damage

You can choose from ten tower types, with different ranges, area-of-effect or single-target attacks, and firing speeds. Towers deal one of five damage types: physical, fire, frost, poison or lightning. These damage types have different effects, such as frost slowing enemies and fire burning them.

Energy and upgrades

Energy pays for teleporting towers and can speed up the recharge of your orbital abilities. Between enemy waves, you gain energy based on how much you currently have and how quickly you cleared the wave. You can use surplus energy at the end of a level to get more upgrades or restore crystals.

At the end of each stage, you choose upgrades that stay with you for the rest of your mission. Towers do not require purchases: once you research a technology, it is yours. The game has no meta-progression, and all units, abilities and upgrades are available from the start.

Orbital abilities

Orbital Strikes target specific areas and must recharge between uses. You can spend energy to use them before they have fully recharged on their own.

Boss battles

Bosses have distinct abilities or characteristics that set them apart from their underlings; they are not simply enemies with more health.
