Game: https://aspect013.itch.io/desert-fantasy-fps
It's made in Unity. It's my private project but want to share it with you and get some feedback on it maybe. You play on a desert map, fighting against fantasy enemies. You can buy weapons while playing with points which you get from killing enemies. At the beginning of the game you also can choose weapons. Every weapon has a different sound. There is primary and secondary weapon. Also there is post-processing in options. If you have any questions, feel free and ask me.
