Decent, better graphics and physical change to guns (like sights appearing, or the gun getting a stock, etc) are needed for a 5.
Also, more fluid gameplay would improve it.
Great game! Music was fun and exciting! It definitely needed to be longer and more difficult.
Nice game. Hints for the game: Upgrade your normal gun until you get the 1st survivor. Then upgrade your wall, until you get the shotgun. Then max out the shotgun & wall first. Then your normal gun. Give every survivor the shotgun & keep them at attacking. Zombies will get stunned from the shotgun. You can (bust must not) shoot, but you don't have to. Your teammates will make the work for you. You don't even have to switch to another weapon for yourself. Just keep at your normal gun. So you'll make it easy to the end.
great xombie game, loved the music felt like i was in the era, perfect
