This guide is for solo only, although if a team follows the same tactics they could do easily as good. I got to round 58 before I got bored and shut it off. This guide also assumes you have some knowledge of the map already. One little tidbit that people seem to overlook: There is a max amount of zombies that can be out, according to how many players are playing and what round it is (not positive about the latter, it could be marginal). Therefore, whenever you kill a zombie, it can appear in the room BEFORE, IN, OR AFTER, the room you are immediately in. Just keep that in mind. BEFORE THE POWER (rounds 1-5): First off and foremost, do not buy Quick Revive or a gun. Also on solo, you want to turn the power on as soon as possible. Run up the stairs and peak out the lone window. You can jump up to see if the box is in there or not. If it is, you may open that door first to hit it if youd like. Use what it gives you. For the first 3 rounds, try to mostly do knife kills (130 points each) and use grenades if you have to. Get to the MP40 room as soon as you can. Youll need 3000 points to get there and have enough to buy the gun. Dont get the Stakeout, youll get more points by shooting with a regular gun. Also, on your way to the MP40 room, take a peek out to the theater; see if the mystery box is out in the theater. Do another 1-2 rounds until you have 2500. Do short bursts with the MP40 and knife if you can for the kills. Open the dressing room and back of the theater and turn the power on. When you get dogs, you can either A) shoot them with the MP40 or B) run around with your knife in circles. The dogs cant turn and attack very easily, so theyre really easy to run around with. I wouldnt recommend this though until you get Juggernog. Run around in circles (via the path you opened) at this point. AFTER THE POWER (rounds 6-10): It really is not necessary to use the teleport portal at this point- although it is necessary later on. Repeat with the MP40 circle strategy. The first thing you should save up for is Juggernog. Then get the Boeing Knife and Quick Revive. At this point you should be at round 8 or so. Zombies should be a 1 hit kill with the Boeing Knife until 11 I believe. Take advantage of this. Short burst shoot them with your MP40 and knife them like before for maximum points. Around 9 or 10, start looking for the mystery box. Leave a crawler (or a regular zombie) so you have time to mess around. If box is in the alley area thats OK; simply make sure you have enough points and start running in a big circle from here on out. TAKE WHATEVER IT GIVES YOU AND USE THE AMMO UP BEFORE TRYING AGAIN. Save your MP40 though. A ballistic knife and/or LMG is the best bet. Dont pray for the Ray Gun. It is a big piece of crap. Rounds 10-30: As soon as you have enough points, open the rest of the doors if you havent already and get the rest of the perks. You will start running this path as seen here: The red dots are good places to start shooting. You will also notice a few points where the path doesnt go the shortest way possible. This is because sometimes the zombies at the front of the pack can be faster than the ones in the back of the pack. By running around a little bit, this allows zombies to bunch up a bit, and this is safer for you and easier to shoot them. By round 20 I would recommend to start using the portal at the beginning of each round and also, start leaving nukes. This is so you dont have to worry about them spawning drastically in front of you. If you DO use nukes or decide NOT to use the portal, book it about halfway around the map before stopping. Then slowly get them lined/bunched up. Slowly start shooting them. Also make sure you spend some time by 20 to get the thundergun. You will use this for the zombies in front of you that you cant juke. Use it until its out of ammo then upgrade it. Also by 25 or so it really isnt worth upgrading anything else. ROUND 30 and beyond: By round 30 it isnt feasible to rely on any sort of gun to kill the zombies. Hence, you will do the following: At the beginning of each round you should use the teleport portal. It is an essentially free way to pack all the zombies together in the beginning of the round. Use the MP40 for points, while reloading (this is the most proficient way to make cash) off the wall, while getting your thundergun (zeuscannon) around corners/stairwells. You will do the majority of killing by setting the 2 electrical traps on the right side of the map, and the fire trap on the left side of the map. Keep in mind you have to BOOK IT after using those traps. By round 50, the zombies literally come out right away almost in succession. This is good and bad- you have to really know what youre doing, but you know you probably wont have any in front of you after you get through 3 rooms or so. If you *really* want to play it safe, or want to practice a bit first, you can run around shooting with the MP40 until the teleport portal is ready to go, and set the trap(s) on the last lap to that. That way, you dont have to worry about them spawning all at once because youll be safe. In many ways it gets easier as the rounds go on; your guns wont kill them, hence, you wont have random zombies in front of you. The hardest part will be to avoid them after turning on the traps (if you dont wait to use the teleport portal- which I recommend if you can, use the traps as often as you can group them together.. rounds get very very long). The two rooms you really have to be careful with are the two rooms on either side of the back side of the theater. It is VERY hard to juke the zombies in these rooms, so have your thundergun ready if you think theyre gonna be impossible to pass. There are tons of different situations you must be aware of. For example: if you had just turned an electrical trap on (from the right side), do NOT sit at the bottom of the metal staircase.. theyll come from the top and trap you really fast. As for the dogs in later rounds- if you have zeuscannon ammo left, then use that. Otherwise, just turn the turret on in the theater. Thats it really. I know this guide was disorganized but hopefully you got the gist.
