Evaluation

Stellar Overload entered Steam Early Access on October 11, 2016 and received five numbered Early Access updates through September 13, 2017. The developer, Cubical Drift, maintained a fairly regular cadence of major updates roughly every 3–6 months during that period: EA Update 2 in December 2016, EA Update 3 in March 2017, EA Update 4 in June 2017, and EA Update 5 in September 2017. Each update expanded the game with new planets, story chapters, gameplay systems, and content. The last communication from the developer of any kind was a small bug-fix patch released on September 22, 2017. Since that date — now nearly nine years ago — there have been no further updates, announcements, blog posts, or developer statements of any kind. The game was never brought out of Early Access and never reached a 1.0 release. The store page has also been delisted (no purchase options are available), though the Steam Early Access flag remains active. Because the game is still technically flagged as Early Access and was never completed, and because the developer went completely silent in September 2017 without ever announcing the end of development or a 1.0 launch, the game's status is deeply uncertain. All evidence points to development having quietly stopped years ago with no public explanation.

About this game

Stellar Overload is an adventure game, in a world made of blocks. The playground, completely open, is made up of different cubic planets. While progressing through the science fiction scenario, you will have to explore all these planets, alone or with others...

The playground



Each planet has its specific set of resources. By exploring them, you will unlock access to new technologies. Merx, the small green planet, is the first planet of the game.

Story and important characters




Stellar Overload is a scenarized adventure game where you’ll go on a quest to free the planet Merx from the yoke of the robots.


Some characters, directly related to the main quest, will give you valuable information to help you progress.

Features related to the story and progression:
- Possibility to customize your character
- Dialogues related (or not) to the quests
- Monitor your quest objectives in real-time
- A progression curve related to the quests but also to exploration
- Planets (and enemies) of different levels

Exploration and craft




While progressing through the main quest, exploring the world and the dungeons, you’ll unlock more and more recipes. These recipes will help you get stronger and go further into the adventure.
You will need raw resources to create various objects (tools, weapons, armors...). You can find these resources by different ways: pick them up directly on the planets, find them in chests or get them as quest rewards.

Exploration and craft features:
- A global map of the planets
- A minimap
- A jetpack to travel through the caves more easily
- Possibility to create a vehicle to move faster
- Different craft stations
- Glowblocks will help you enlighten the caves
- Different levels of gauntlet in order to pick up the various blocks of the game
- Teleportation (within a dungeon or between planets)
- Semi procedural dungeons
- Evolving music and soundscape based on the day-night cycle

Combat




To defend yourself against your enemies, you will rely on the creative talents of some important characters in the story, and learn how to create weapons and armors.


The Block-Thrower is an exotic weapon, it can load any of the game’s blocks and throw them at enemies. Depending on the nature of the blocks, damage and effects will be different. Damage aside, if you throw a Glowblock against a cave wall, it will enlighten the cave.

Features related to fighting in this early access version:
- 5 different weapons: the pistol, the rifle, the Block-Thrower, the sonic carbine and the grenades
- 1 armor to greatly reduce damage
- 6 different enemies (Arkuloids, Cognitrons, Legionnaire robots, Plasma turrets, Tesla pylons)
- A boss in the fortress

Construction




Since Stellar Overload is a game made of blocks, the construction (and harvest) is an important aspect of the game.
You can build all types of structures but also vehicles, which will facilitate the exploration of the planets.
A creative mode is available, allowing you to unleash your imagination without worrying about the scenario.

Construction features:
- 6 different shapes of blocks
- Easily place and destroy walls (straight or sloping)
- A tool to "paint" the targeted area with a certain material (adjustable size)
- A tool to save a construction and place it elsewhere ("copy/paste")
- Possibility to define an alignment grid (to facilitate the placement of shapes)
- Undo / Redo : very useful in creative mode!
- More than 200 different materials

A few numbers in blocks



Merx, the first planet of the game, which is also the smallest, is 1200 blocks long per side, with an area of 1.4 million blocks for each face.
