This game is really fun but lacks "replayability" because the game quickly becomes easy. The juggernauts on every round is a decent balance for the huge open-spaced layout of the map but their threats rarely last when guns like Thundergun, Gravity Mine and drops such as Instakill and Nuke one shot them. It's a shame because they somewhat make the game more engaging when you are hording zombies. Furthermore, each round graciously gives the players a combination of random perk, random weapon, pack-a-punching current weapons and a max ammo drops. Suddenly, conserving ammo and playing smart is thrown out the window altogether (that crazy perk temporarily enabling unlimited ammo is funny the first few times though).
I suggest making the Jugg invulnerable to the instakill weapons and drops, and adding more juggs (or even a Panzer Soldat!) for every 5 rounds at least. That'll keep the players on their toes! At any rate, this is a great map and I appreciate sharing it with us!
