Major Update 0.8.3: Destructible Objects and Secret Rooms

Thank you for your support, feedback, and comments! We are very excited and dedicated to making the game better with each update.

Destructible Objects:


- Part of the environment is now interactive. You might encounter destructible alien eggs, barrels filled with explosive mixtures, cardboard boxes, and barrels of sticky fuel. They can either help you in battle or cause harm, serving as a source of loot or trouble.

Secret Rooms:


- Now some walls in the underground stations are destructible (you can identify them visually by cracks) and lead to small secret rooms. These rooms may hold extra loot, but be careful.

Other Improvements and Fixes:


- Now, if your weapon runs out of ammo, it is indicated by an icon on the weapon switch icons.
- New corridor variations have been added in the Reactor Complex.
- Fixed an issue that caused delays when switching to melee weapons.
- Fixed an issue where the mouse cursor sometimes wouldn't display after returning from the game to the main menu.

Boss in the Marshes and Online Co-op:
Unfortunately, the mechanics and limitations of the bosses do not currently meet our expectations and the interest we have placed in them. Therefore, we have decided to add them to the game after release in order to avoid delay with other content and the release date. Additionally, we must postpone online co-op for an indefinite period; this feature will not be available during Early Access. We would love to know if you are looking forward to online co-op.

Stay tuned for updates.

Just a couple of minor things left to fix before we get the green checkmark: - The scale of the main menu and story notes is slightly small, but still comfortable to read. - If you connect an additional gamepad after the game has already started, control currently switches to it.
