Basics

spawn rush

Pretty self-explanatory, the more you survive, the better the reward will be.

After some time, almost every zombie will start sprinting. I recommend to quickly pack the zombies and train them around the tree. Also kill the walking zombies.

Train strategy

The exit (zombies won't spawn here, so if you play co-op I recommend you that one player do the train strategy, and every other players stays in the gate)

Each 10 seconds that you survive in the spawn, you get access to a new reward, here what you can obtain by surviving. You can claim your reward at any point of the game.

10 seconds : Double Points

20 seconds : Max Ammo

30 seconds : Fire Sale

40 seconds : Free weapon

50 seconds : Free Pack-A-Punch weapon

turn on Power

The power is quite hard to miss, just progress into the map, and you'll pass by the power.

Be careful tho, the very next round you turned on the power, the special zombie will spawn.

Panzerhound

In the middle of the next round after turning on power, the mini-boss of this map will spawn.

That boss being the Panzerhound.

He will run at you and throw flames like a regular Panzer.

Find the Bazooka that will be shown across the map.

Shoot the Panzer 2 times to kill it (be careful, its hitbox is kinda weird, the optimal strategy to me is to wait for it, at the top of the stairs next to the MG-trap and shot it from above).

Once killed, he will drop a Max Ammo and spawn 5 round after.
