A gigantic update to Celtreos!

“Hard Difficulty” Setting


Enabling this new setting makes the game significantly more challenging!

  • “1UP” power-ups NEVER spawn
  • Defensive items such as “Shield” are far less likely to spawn
  • Achievements do not give invincibility (though the Achievement still counts)
  • Small round bullets are invulnerable and must all be avoided!
  • Most projectiles are stronger and harder to destroy
  • Much longer cooldown after using a Charge (“Bomb”, “Lightning”, etc.)
  • Negative items appear more frequently
  • Several enemy attack patterns change, and many are also faster
  • More enemies spawn, and some walls may also change

Updated Music


There have been significant soundtrack improvements, updating songs such as “Disposition”, “Assignment”, “Evasion”, “Excursion”, “Confrontation”, “Portension” and “Flow”.

Artwork, Animation and Effect Updates


There have been minor tweaks to a variety of effects, including explosions and shaking.  Some of the UI has improvements, like certain icon artwork and text sizes.  Background contrast has been tweaked in stages like “Alien Ocean”.  The “Predator” weapon has also improved.

The “Colony Evacuation” and “Last Stand” stages now have water lines that cause splash effects when the water is hit by things like bombs, certain bullets and debris.  This opens up a new line of evasion, as you can potentially avoid being hit by flying further down than the water impact point.

Test Stage Updates


Wide-area-effect cooldowns have been removed when “Test…” is used, allowing more rapid experimentation with those abilities.
