Updated to 1.86

A big update to Celtreos!

New Story Artwork

The introduction to the game now shows a few background pictures while the story text scrolls by.

General Artwork and Animation Improvements

Several effects have been tweaked, such as explosions and power-ups.  Certain enemies are now more animated. In many pieces of artwork (especially those with gradient colors) the quality has increased.

The XP display in-game has been slightly improved.

Updated “Alien Ocean” Stage

The “Navigation” song has been refined further.  Also, background artwork for this stage has been enhanced in various places.

An enemy in this stage has been modified to emit “bouncing” projectiles in many directions, instead of its previous laser attack.  These projectiles are now also emitted during certain boss fights!

Arrow Keys

The left, right, up and down arrow keys can now be used for keyboard input (with the same effects as the “A”, “D”, “W” and ”S” keys).

French Localization

Several cases of English-only text in the “trophy room” have been fixed, now available in French.

New EXP Tiers

Each weapon slot now has 5 Tiers instead of 4, with a new set of updates possible for each slot!  Look for the following:
  • Enlarge (destroyer weapons): Always fire larger projectiles
  • Expand (default and sideways weapons): Cover a larger area
  • Power Up (opposer weapons): Do more damage
  • Range Up (locator weapons): Detect enemies from further away
  • Resilience (default weapons): Prevent reduction below a power level of 3
  • Waves (multiway weapons): Periodically fire larger projectiles
New EXP UI

There is now a bar underneath the main Tier display that shows more granular EXP acquisition, split into two parts.  The first part is static, aligned with any obtained Tiers, showing EXP that has already resulted in awards.  The flashing range shows “pending” EXP that will turn into a Tier award at the start of a future stage.  This should make it easier to understand when you are close to an upgrade, and you can adjust how much you invest in weapons accordingly.

Artwork and Animation Updates

Several weapons, icons, ships and other artwork have been slightly improved.

Updated to 1.84

A gigantic update to Celtreos!

Weapon Proficiency (EXP) System!

You can now improve weapons as you play!  Each time you start a new game though, EXP resets to zero.

Every class of weapon has its own EXP value that accumulates over time.  It does not matter which Series you use: all weapons of the same class will continue to build up EXP for the weapon slot they are in (each weapon array has exactly one weapon of each class).  For example, if you started improving Seeker in one stage and switched to a Series that contained Phaser in another stage, both of these will improve the same weapon slot.

Weapon slots have tiers. indicated by a bar underneath the new XP display in-game.  Each time you gain a new tier, you receive the associated bonus or weapon update.  Although some effects can apply to several weapon slots, others are entirely unique; keep improving your weapons to see what they can do!

Tiers can only change at the start of a new stage (when bonuses are awarded), even though EXP accumulates continuously during gameplay.  The EXP scale is also not linear; for example, it is much harder to go from Tier 3 to Tier 4 than it is to go from Tier 1 to Tier 2.

See the help function in-game to learn all about weapon classes, tier bonuses and more.

New Achievements

Several new Achievements have been added to the game, related to the weapon proficiency system.

Updated Music

The “Evacuation” and “Mystery” songs have been refined further.

Artwork and Animation Updates

Minor tweaks have been made to a number of animations and effects, such as the impact animations for the Beam weapon, certain explosions, and player ship exhaust colors.  The large asteroids in the “Planetary Approach” stage are now more varied.

Gameplay Updates

Weapon mounts now show their current positions and trajectories with new indicators on your ship.  This is especially helpful with moving mounts such as Crossover and Circular, and when multipliers are temporarily in effect, as it is easier to see where shots will be fired from.

Also, several enemies are now tougher to destroy in “Hard Difficulty” mode.

Some minor display glitches have been corrected.

Updated to 1.82

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.
