Hello everyone,
Russian player (LJ user) crack_usaf was kind enough to save the Test 1 (new) gun sounds for us. Sadly, the Hellcat/Jackson engine sound is not available. You can get the gun sounds here.
Installation is rather problematic – I tried to simply use them as a mod (add them to the res_mods/0.9.0/audio folder), which kinda deleted pretty much all the old sounds (I heard only gunfire). I don’t think that’s right and I am not sure they work in the 0.9.0, better to wait for 0.9.1 with their installation I think.
