| Updated to 2.4major A big update to Celtreos! Major Artwork Improvements A huge number of changes to game artwork have been made, mostly large but some small as well. All space backgrounds have improved, with brand new planet artwork and the introduction of some nebula effects (this also is visible in things like the introductory story scene). The city background of “Colony Evacuation” is completely new, with more… | 25640786 | |
| Updated to 2.2major A big update to Celtreos! 3D Effects There has been a huge focus on improving 3D effects and layering in backgrounds, with some accompanying performance tweaks. This is most noticeable in stages with walls or large background objects like cave rocks. Basically, things that used to look very flat will now have significant depth. As you approach and go beyond things like walls and tunnels, there… | 24134772 | |
| Updated to 2.0major A big update to Celtreos! UI Updates There are new bidirectional rocker buttons in several panels, typically as “-/+” buttons. These take up less space but also consolidate focus so it is more efficient to traverse controls using game controllers or the keyboard. In most cases these new buttons enable moving in multiple directions through settings that previously could only be traversed one-way… | 21231898 | |
| Updated to 1.99major A big update to Celtreos! New “Lancer” Weapon A new weapon “Lancer” has been added to the Devastator Series, and it can also be used in custom arrays.

| Updated to 1.96major A big update to Celtreos! UI Accessibility Updates “Celtreos” now supports multiple text sizes : in the option screens, in story pages, and in the score display during the game. This can also affect layout, e.g. story pages can be arranged differently to suit the new text size or some UI text labels may wrap to multiple lines. By default, this will mirror your system-wide Accessibility settings… | 20254476 | |
| Updated to 1.94major A big update to Celtreos! Music Updates Many songs have been tweaked, including: Evasion, Mystery, Portension, Opposition, Trepidation, Diminution and Establishment. Gameplay Updates There is a new weapon mount type, “Reverse V”! Similar to “Crossover” but focused on the reverse angle with a wider expanse, this moves your weapons fire along a rotated V path to cover primarily the area behind yo… | 19293579 | |
| Updated to 1.90major A big update to Celtreos! New “Lateral” Weapon A 5th sideways-class weapon, “Lateral”, has been added to the Plasma Series (and can be used in custom weapon arrays). This fires modules above and below your ship that damage anything they touch, while also periodically firing forward or backward from the current locations of the modules. Furthermore, this weapon has 5 variations because it fires… | 17147235 | |
| Updated to 1.89major A big update to Celtreos! Enhancements to “Jungle Cave” The tree/wood artwork in this stage is now significantly more detailed. Also, foreground logs that are obstacles are brighter so they are easier to avoid. The stage layout has been tweaked in a few places. Clouds You Can Shoot In the “Dark Nebula” and “Orbital Defense” stages, certain clouds are now mostly opaque and can hide enemies and i… | — | |
| Updated to 1.86major 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 disp… | — | |
| Updated to 1.84major 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 exact… | 15044871 | |
| Updated to 1.82major 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 stronge… | — | |
| Updated to 1.80major A gigantic update to Celtreos! It’s been a while since the last update but this one is worth the wait. New “Bumper” Defense The “Plasma Series” now has a unique defensive ability, “Bumper”. This item makes it extremely unlikely that your ship will be destroyed by walls, and it will also push your ship out of the way of such obstacles (be careful though as it provides no protection against enemy… | — | |
| Updated to 1.79major A big update to Celtreos! New Progress Tracking Mode There’s a lot in this game, and you don’t want to miss anything. Now you can be sure you haven’t, using a new mode that keeps track of the major things you have done! Use the new “trophy” button on the main options screen to reach this mode. In the top-left corner of this screen is a basic percentage of overall game progress (this is also dis… | — | |
| Updated to 1.77major A big update to Celtreos! New Stage “Dark Nebula”! Now the fifth stage immediately after “Hyperspace Pursuit”, the new “Dark Nebula” stage is shrouded in the clouds of a nebula in space. Bullets and enemies will be harder to see, in this fast-paced game of hide-and-seek that ends with a creepy new boss! Other Soundtrack Improvements In addition to the brand new song “Mystery” to pair with the “… | — | |
| Updated to 1.76major A big update to Celtreos! New “Skip Stage” and “Retry Stage” Options From the Paused screen, it is now possible to retry the current stage from the beginning (retaining score and weapons), or skip the stage entirely! If you reach the final stage and there are still skipped stages, the game will loop back to unfinished stages until you complete them. Updated Artwork and Animation Several enemies… | — |
