After playing the game more I have since figured out the problems I had and I take back all my complaints . The only thing that really annoys me is how the player keeps getting stuck sometimes even on walls with no real reason for them to be stuck. I also wish I could use more legendaries at once perhaps once you reach a certain level instead of having so many of them that you can't use . and ofcourse there's still the classic bug where you can't finish a mission because aliens are in the walls

Hello! thank you for sharing your idea about auto sell button, will think about it. What about ammo - how it happen? Not when your ammo is full?

I really love this game.Its so good and interesting, especially when you have really good weapons and they get greater strength when you infuse them.But my only problem is that,the battle pass costs too much.I would have upgraded it but all that just for a game?,so they(the programmers)should reduce it a little

hi devp... can you make a setting for players to choose whether to play solo or in groups (partners)... I think for advanced players it is more challenging and fun to play solo... and having a partner is only suitable for newbies
