We have added lots of new stuff besides the guns and shooting! New location types, so your not just on the highway, but inside the city, in city parks and more, character leveling up, upgrading as you drive (stop by a garage to replace your tires for example), new grapple mechanics, a revamped and far more deadly mutant zombie, new types of upgrades like weapon attachments to your vehicle, and much much more!
We are finishing it up & polishing everything we can. We had a deadline of Halloween but we'd much rather put together the best game possible rather than rush it. But it's close to completion!
