i loved this game for the fact that i like how its in flash but it looks 3D i hope that someday in the near future the dev gets backed by a company to have these games go full force with more detail with models,weapons,vehicles,enviorments and just everything. ill always come back to this game to see that a determined developer made a game that so many people loved.
this game is very easy to learn darker areas of the map are "cover" which slow your troops down and speed up the infected but engaging the infected while your troops are in cover and the zeds arent provide a accuracy bonus and the zeds wont follow you as far if you must retreat but if troops are not in cover and zeds are accuracy will be greatly decreased and zeds will follow closely behind you if you retreat.
-in missions 5 and 6 keep your rocket squads inside the reinforcement line and send a MG truck to them they will also receive more troops while the truck is being built (rocket squads receive troops more slowly then rifle squads)
- if your squads engage in hand-to-hand combat the squad leader can take on ten at a time but if the normal troops get attacked by two or more zeds they will insta-die
-after mission 2 zeds with start to run closing the distance between your troops much faster, counter this by falling back NOT RETREAT and fire as soon as possible
-engaging in hand-to-hand while falling back will lead to the death of the squad, if they get to close charge to have the best chance of survival for your troops
-having a vehicle with a tank turret or MG will always shoot even if your retreating taking out 1 or 2 more infected making it easier for the second encounter with that hoard
-in the later missions build 1 vehicle with a artillery battery on it, this will take a minimal 8 mins and 20 secs, the cannon will not fire unless the hold order is given, when it does fire it will devastate the zeds on every lane, it also comes with a bonus soldier with a pistol
-pay close attention to the descriptions of each vehicle you want built as some are only good on roads while some move slow on all terrain
i hope these tips are helpful to anyone who reads this, have fun killin the undead soldiers!!!
