Ok, I don't know if these are tips or if its a guide but oh well. I'm very bored and was looking through the casual maps and found a crap load of infection maps that had ridiculous armories. Still being bored, I decided to make a guide. This was inspired (sort of) by the guide to infection maps. If you scroll down to the bottom, there will be tips on placing armouries in casual and competitive maps.
What is an armoury:
An armoury is nothing more than a collection of resources or a place where weapons are kept.
What Armouries can do:
Armouries can possibly make or break a map. If applied correctly, they can create very unique gameplay and make your map a lot of fun. If applied incorrectly, the humans can be too powerful and the zombies won't be able to kill any humans. If it's in a casual map, a team can lock the armoury in slayer and easily win or camp the objective and make it ridiculously hard to get.
When to apply an armoury:
When in doubt, don't even put in an armoury. Only use one if you are sure you need it. Sometimes it is better just to scatter weapons about the map. Never place an armoury if humans have unlimited ammo. It will be to hard to kill the zombies. Also, some armouries may only work if the gametype is altered, for example, more shields to the zombies.
The structure of an armoury:
The first thing when designing your armoury is asking yourself if there are more than two ways into the armoury. Having only one or two will result in the humans easily being to camp inside of it and the zombies will never be able to get in. You want to make it so the humans do not want to stay in the armoury. You want them to just grab weapons and seek another place to camp. Have multiple access points so if the humans decide to stay in the armoury, it will be very difficult to hold out. Armouries that are out in the open can sometimes work quite well, but other times, the zombies won't be able to get to the humans if they camp in the open armoury. If you ever do decide to make an armoury in the open, make sure there are still multiple access points as well as some crates or little cover so the zombies have a chance to kill the humans.
Where should you place an armoury:
Where you place an armoury can have a huge impact on how your map plays. You don't want the humans spawning in one because they will be able to have a lot of time to pick the weapons they want and most likely, they will be able to camp the spawn. But at the same time, If you make it at the zombie spawn, It will never be used and it will have been pointless to make. I find the best place to place an armoury is where humans can get to it easier than the zombies, but the humans are rushed because the zombies aren't to far away from it. That way, the humans will be able to pick up weapons, but won't have time to make sure that it is the one they want for sure. If they do take to much time picking up weapons, the zombies will kill them. Also, placing an armoury at a high point is bad as you will be able to look down on the entire map.
What to place in an armoury:
Armouries are a collection of resources so that is what you want in it. Resources can be weapons, grenades, equipment, and it can even include vehicles, as seen in the map convoy tunnel. Depending on the weapons, an armoury can be easily camped even if you have multiple access points and it is on low ground. (Convoy tunnel is a great map, but the vehicle part in the beginning is very easily camped. Put someone in the tank turret and someone watching the teleporter.) The stronger the weapons in an armoury, the farther away you want the humans to spawn from it, while the weaker weapon armouries, you can have closer. Always be careful while placing fully automatic weapons. In a lot of situations, they are a lot more helpful than semi automatic weapons because it allows you to kill more zombies without reloading. Your map and its size will tell you which kind of weapons to place in the armouries. If you want weak armouries, an open map will have SMGs, Spikers, ect. A closed map will have BRs, Carbines, ect. If you want the armouries to be strong, reverse each of those. Power weapons should always be placed with care and few spare clips. I can't tell you how to place power weapons because it soley depends on your map geometry and how the game plays. One open map might not work with rockets, but another open map may work with them.
Equipment combined with weapons isn't a smart thing because you can plug up doorways resulting in the zombies trying to get passed the obstacle and in that time, they will have been shot down. Some equipment can also let you escape very easily. Try avoiding flares and deployable covers in an armoury with weapons. Try to place those in an armoury closer to the zombie because if you want extra cover, you will have to risk your life getting it. I find that grenades can ruin armouries as well because you can keep picking them up and you can block doorways with them. Make sure grenades have long respawns. If you must put certain weapons, equipment, and grenades, make sure they have a long respawn or have no respawn at all. Always keep limited ammo in the armoury. It is nothing more than a temporary holdout point and you want the humans to eventually have to move. If you stack the armoury, the humans will stay in there the whole time and it will create boring and repetitive gameplay.
Armouries for maps other than infection:
If you are making a map for an objective, never place an armoury near the objective or it will be much easier to protect the objective. Try placing it in a far corner of the base. You also don't want the armoury in places where people run the flag as they can grab a few weapons while running the flag, which will end up making it harder to kill the flag carrier. Keep them tough to get to and off the beaten track. For a slayer map, You will want to make multiple armouries so you can't gain the lead, and sit in one the entire time. Never place the power weapons in the armouries, and when in doubt, don't even make one.
Well those are my tips/guide. This is more for beginner mapmakers but advanced mapmakers can still get help from it. I used the search button and didn't find a guide on armouries so if there is one i will delete this.
Well, i'll go back to being bored. Tell me if you have any tips and tell me if you think some of this is wrong.
