Our take on Mass O' Kyzt

The store copy gives substantial attention to the setting and enemy-modification mechanic, while the stated objective remains focused on destroying as many Kyztlings as possible. Sparse supplies and difficult recovery also shape the described combat loop.

What is Mass O' Kyzt?

Play as an astronaut on Ky, the home planet of the psychic Kyzt hive mind.

This 2D side-scroller places the player in an arena against hordes of Kyztlings, with the objective of destroying as many as possible before being overwhelmed. At intervals, choose whether to make the enemies stronger, faster, or tougher; the selected change augments the Kyzt forces. Supplies are scarce, so recovering from damage is difficult. Defeated Kyztlings provide Special Energy, which serves as ammunition for more powerful shots and can produce unusual weapon effects. The described gameplay focuses on surviving the alien assault while awaiting rescue. The demo is presented as forthcoming rather than available.
