I played the flash version, loved it. I was excited for this early release and have not been disappointed. This game is simple, addictive, and (surprisingly) thought provoking.
-Characters actually loose life when they don't eat
-Weapon knockback feature
-Reloads and/or heals not completing on level transitions
-Map navigation makes portion of the game slow and tedious
-Level length (would love to see some 3 or 4 transition buildings to add to difficulty)
-Supply/Weapons are never obtained where they should be (gun store/police station never have any guns). Would be cool to know exactly where to expect to find certain types of items. Would make map navigation more strategic.
-Supplies are maybe a little too scarce (while I realize this meant to be a zombie survival game, 2 to 0 supplies per building make it almost impossible to keep the basic 4 character team build from starving each round after a while). If you want to have more than four players to focus on research, forget about it. I very rarely keep more than 6 players on my team for this reason.
-Not being able to walk and reload at the same time. increases difficutly, but not very realistic.
The "random events" system at the end of some levels is what completes the game for me. After a few hours, the game can become fairly stagnent. Difficulty increases, but if you get the hang of weapon combos (2 ar's, 1 shotgun, 1 melee) and creating choke points, you can breeze through most of the levels with little difficulty. And then, once the game starts to become mechanical and get boring, it throws an uncontrollable wrench into your system: "You hear moaning behind the door...A zombie horde is onto you, you manage to get away but now all survivors make it." All of a sudden, you loose your best weapon, you loose your best player, and you have to completely reevaluate your approach.. Do I need to go find a merchant?. Do I need to go find a survivor?, etc.. BRILLIANT game mechanics to spice things up in a no-going-back zombie game. I would love to see further development in this portion of the game.
My biggest complaint about the game mechanics would have to be with the map navigation. As the cities get bigger, only being able to move to adjacent buildings makes the game progression very slow and tedious. At certain points in the game, you just want to move across the map quickly, especially when you have alreayd cleared 98% of it. It would be nice to be able to move to any building that you have already occupied, no matter where it is on the map or how far you are from it. This would expediate th e most tedious portion on the game and let you get into the core gameplay quicker.
All-in-all, a very good game. For the price, I would recommend it.
