Update 2.7 for CS: A Mix of 3 Eras file

Important: I strongly recommend you to rebuild the sound cache after installing this update in order to prevent audio glitches in-game. To do this you need to go to your mod folder, then "sound", and delete "sound.cache".

1. Updated M249 firing sounds to the latest CS2 sounds.
2. Improved shading of the viewmodel textures for the HE Grenade and Smoke Grenade.
3. Improved shading of the viewmodel texture for the Deagle.
4. All weapon firing sounds now overlap, this makes them sound a lot more like they do in CSGO or CS2 when rapid firing or when firing a full auto weapon.
5. Updated the look of the in-game menus.
6. When you select a weapon by the number keys, a quiet moving suit sound plays, just like in CSGO or CS2.
7. Increased accuracy of footstep sounds.
8. Updated UMP45 boltslap sound.
9. Added a new starting intro video.
10. Improved the appearance of the in-game chat window.
11. Fixed a bug where the grenade throwing sound effect was being cut off by the grenade announcement sound.
12. Fixed an inconsistency with the concrete bullet impact sounds.
13. Increased the volume of HE Grenade explosion sounds.
14. Added new muzzleflash and metal bullet impact sprites.
15. Fixed the silenced USP sound being cut off by the reload clipout sound.
16. Updated the local server MOTD image to the ModDB banner you're seeing on this page.
