This game doesn't play audio outside of music. Games with big parts of them not-functioning should not be sold. And before anyone chimes in, no, I am not going to configure my PC's audio settings to compensate. Because I shouldn't have to have to do any work on my end to get the game working. That is the reason GOG exists, to fix problems like this and make old games playable without the player having to do anything.
The game crashes if you set the resolution up to full and can only be fixed by uninstalling and reinstalling. Additionally, some times when you pull your weapon out it will automatically start firing either main or alternate fire OR it won't read the input when you want to fire - this has caused me to shoot my allies or not be able to shoot my enemies several times. Additionally, the Borg will adapt to your weapon fire but without explanation the secondary on your starting rifle will work even if they've adapted to the primary fire of it (this doesn't work for the alt of the hand phaser) which is just confusing. And for some reason your allies have a melee option that you don't , which is annoying because the Borg quickly become adapted to everything you have but your allies melee option still works. I've just finished playing the first one and loved it, but this is a major let down. I'm not even past the first level and I've lost any interest in going further. It also seems to lag no matter what settings I use in some areas.
