zombies, cars and tech retextures (music and menu panorama)

We decided we needed a custom menu splash screen and made a recourse pack for zombies, cars and tech ! it's really good :)

All music changed to almost sad feeling and sometimes upbeat soundtracks to make a rollercoaster of emotions !

splash screen at the start of the game changed to a screenshot of the zombies, cars and tech pack to create greater immersion :)
