Early Access Game

Get instant access and start playing; get involved with this game as it develops.

What the developers have to say:

Why Early Access?

“Currently, the game is in a minimum viable product state. This means that we are still fully developing the features and systems that drive our game and want to get feedback from players to further enhance the game based on the community. This is why we want to have an Early Access phase on Steam.”

Approximately how long will this game be in Early Access?

The current state of the project does not allow us to determine for how long Stellar Survivor will remain in Early Access.
Since Stellar Survivor is an academic project, the game is bound to school deliverables deadlines. Once these deadlines have been met, the project will continue development and more updates will follow improving the Early Access version and working towards a full release.”

How is the full version planned to differ from the Early Access version?

“Currently, the Early Access does not contain all the desired features we wish to have in the game. After the Early Access, we plan to have the following features in the game
  • All aliens have more animations
  • Missions will be available
  • Co-op will be available
  • All aliens have unique models
  • All aliens have textures and (particle) effects
  • Improved particle effects
  • Aliens will have new SFX
  • The playable map might change
  • The weapons have unique SFX and UX
  • There will be more options available in the settings menu
  • The overall game will be more balanced
  • Game will be improved performance

What is the current state of the Early Access version?

“The current Early Access state has UI that will be updated as well as the world will have different lighting and textures. The map layout might change and more vegetation, foliage and animation will be added. The alien spaceship and the spawning sequence of the enemies is an early version that will be updated.
More details:

  • The player will learn how to move the character around the world
  • The player is taught how to gather resources and spend these into building traps and upgrading them
  • The player is introduced with the Powercore they have to defend and taught how to get health from the Powercore
  • The player is taught how to switch weapons
  • The player can skip intermission time by pressing Enter

  • Only Extraction Mode is available and other missions have been disabled

  • Co-op is being developed but not yet enabled in the Early Access until proven working properly

  • Not all alien models are in the current build, some enemies will not despawn correctly
  • Enemies currently only have a hit and death sound
  • Enemies currently only have a running animation

Known issues
  • Spriting does not function as intended
  • Ground textures quality is inconsistent
  • When pressing Escape in the game over screen, the mouse cursor will disappear
  • Sometimes in the tutorial level, the player is instructed to collect six resources. However, in order to continue the player needs to collect at least eight
  • It is possible that in the Tutorial level there are insufficient resources if the player immediately gather all of the available resources
  • The player can affect the wisp trail system (arrows showing the walking path of the enemies) in all levels
  • In all levels, the alien spaceship disappears with some light effects still remaining
  • Players can immediately press Enter from the start of the Tutorial level
  • Framerate may significantly drop at certain moments
  • Opening the settings screen from the main menu does not work
  • One texture in the main menu scene is missing
  • Upon launching the game, it might crash

Will the game be priced differently during and after Early Access?

“After the Early Access, the game will remain free (no microtransactions).”

How are you planning on involving the Community in your development process?

“During the Early Access period of two weeks, the developers will communicate with the player base in order to properly enhance the systems and features that drive the game. We will also use the data to balance the game more.”

Patch Update 1.1

To start off we want to thank everyone that has played our game over the last weeks! We received a lot of very valuable feedback that we can really use to improve our game.
For this patch, we put our main focus on fixing critical issues and problems within our game, in the future we will put more focus into adding more content in terms of multiplayer and missions.

Vote for new missions
Since we are very grateful for everyone playing our game we really want to get you guys involved in the development process. That’s why we are hosting a poll where you can vote on what missions we will be focussing our development on. The poll can be found here:
If you have any other mission or gameplay suggestions feel free to share them on the steam discussions or join our Discord to reach out to us!

Major updates
- Players seemed to not be able to get past the ‘Disclaimer’ screen. We investigated this issue and expect it to come from our game not detecting the proper screen resolution, we have implemented a fix for this that will hopefully solve this for most players. You now also don’t have to correctly press the button but can press anywhere on the screen to bypass it.
- Since release we have been working hard on improving our AI based on community feedback, with this patch there will be major improvements, some of these improvements will fix that enemies no longer run away from players and they will also start targeting walls. We are of course still making improvements to this system and listening to feedback but this should already be a big step in the right direction.
- Thanks to player feedback we have adjusted the game balancing to create a more challenging experience in the later stages of the game. We are still looking to improve this so feel free to give feedback on this! One of the main changes for this will be that adding multiple of the same trap will increase their price. (More info explained below)
- As a much requested feature, we have now added a mouse sensitivity in the settings menu, we are still taking input on this but it should be a big improvement for players that were struggling with this before.
- Additionally, we have done some internal testing to improve the game's overall performance.
Smaller updates:

- Fixed an issue where the sniper would hit the same enemy multiple times.
- Half walls can now be destroyed by enemies.
- Enemy ship will now always be invisible when they are not active.

- When a player falls there will no longer be audio that makes it sound like the player taking damage.
- If a player let’s go off crouch while underneath a structure he will no longer get stuck.
- Players will no longer be able to destroy their own traps by shooting at them.

- Added sound effects for crystal gathering from enemies.
- The PowerCore now plays a new sound when under attack.

- Improved the damage of the Assault Rifle as it was overshadowed by the Shotgun and Sniper Rifle.
- Shortened the detonation delay on Mines to improve their damage dealing capabilities.
- Adjusted the rotation speed and target location of Turrets for more accurate enemy tracking.
- Improved the stats of the base Turret. Its high price is now more justifiable.
- Adjusted the stats for the Tier 2 and Tier 3 turret so their power level increases more gradually.
- Base traps will now become more expensive the more you place of them.
- Rebalanced the waves for the tutorial and extraction mode for a more challenging and less monotonous experience.
- Lowered the damage each enemy does to the power core to prevent the new wave balance from making the game too unfair.

- Players can no longer build directly on enemy spawn locations.
- Players can no longer build inside electric traps anymore.
- Added a small area directly around the powercore were the player is not able to build.

- Improved the world environment.
- The environment for the main menu has been updated.
- Removed certain rocks that were blocking enemy movement.
- Fixed some parts of the terrain to prevent the player from getting stuck.
- Improved collision on the overall world.

- When traps are on cooldown they will now display a red colour.
- Added warning sound which plays when an enemy gets close to the power core. This should offer more feedback when the power core is under attack
- The effect that the player receives when he heals from the powercore has been updated.
- Icons on the mini-map now only display at certain zoom ranges.
- The build version (seen at the bottom right of your screen) now matches with the actual version number.
- The ready/play buttons in the main menu are now clearer and won’t overlap with the default steam notifications position.
- In single player, the player will no longer have to ready up before he can play the game.
- Improved minimap colours and clarity.
- The powercore health will now always appear above the powercore instead of below it.
- In the settings menu, the player can now hide the on-screen buttons if he wants.
- The player can now also has an audio slider in the settings menu.

- The player now has to collect 15 crystals inside the tutorial map to match the cheapest trap.
- The tutorial has an improved environment.
- The first tutorial wave now contains an extra medium enemy.
