Lol, I got zombies walking on water. Happens when you detonate the bridge about the same time the zombies appear from a zombie hoard attack on that bridge.
Some tips, zombies do well in hordes, not so well individually. Zombies have no collusion detection, meaning 100+ zombies can be stack on top of each other. Also, zombies can turn mass amounts of survivors into zombies very quickly. That being said you better off having five survivors on five different sniper towers then five survivors on one sniper tower. Try to split the zombies into small controllable waves.
A nightmare scenario is to try to quickly built two sniper towers with 50 ammo each fully upgraded max distance from the nearest depot, 7 squares, with no barricade in front to face a horde of zombies and 11 survivors each. The sniper towers won't finish in time and the snipers won't be able fire. The zombies with demolish the sniper tower and turn all 22 snipers into 22 more zombies.
Beat eight stages so far just brute forcing every possible solution, is there a faster way to solve these puzzles? This feels a lot like exit/corners there is no trick or pattern to the puzzles.
