If you want a summary of what's new in version 8:
-Enlargement of the map (a forest area)
- Appearance of drones (allow you to save your equipment)
-you have a kind of "small base" before leaving on the demo map, where your goal is to get to the other exit of the area alive
-Enemies have a reworked AI (can now detect via your weapon's lazer) and can steal your gear (even what's already equipped) when they knock you out or if you're already constrained by something else
- Appearance of healing areas to heal you tentacles or eggs in your body
-An IDE to see the progress curve of the difficulty of the game (evolving difficulty)
-Less loot on the map as well, as well as the rarification of merchants and crates
-And a save system now! with some clear data system
It's what I see for the moment, so, have fun!
