Here's a genuinely serious one about a problem that's pretty niche;

The design of Linear infection maps has sorely declined from the quality found in Reach, 4, H2A and probably even 3.

I'll preface the maps that have come out in Halo 5 are incredibly well forged in terms of visual design and scripting. The forgers in this game are incredibly talented in that regard *but* in terms of map design in terms of gameplay they are incredibly lackckluster at best most of the time.

I'd like to give [Oakley Hi Def's "Origins' 1 The Labs"](https://www.youtube.com/watch?v=mgNo7y9fDSc) map as an example of how map design was in the past and compare it to a popular linear infection map from Halo 5: ["Escape the Underground"](https://www.youtube.com/watch?v=yLmsoYRLGtk)

First let's talk about the different game type settings:

Origins starts survivors with Assault Rifles. It gives the Zombies enough a decent movement speed advantage over the humans without feeling overwhelming and lets them absorb a fair amount of bullets before going down without being "tanky". Ammo is also limited, but weapons are left over the map for players to scavenge. What these settings do is encourage teamwork and smart tactics for both sides. Humans must focus fire and move as a group to avoid getting overwhelmed or running out of ammo. Zombies have a bit more leeway and can push up on humans tactically, especialy since they have the cover to advance, as I will discuss further later.

Meanwhile in Halo 5, Humans start with Shotguns, giving zero incentive for teamwork. Zombies on the other hand are insanely fast glass cannons, and for reasons pertaining to the map design, it turns them into little more than player guided missles. Furthermore, and to a lesser extent, since Halo is a game best played on lower sensitivities, the speed at which players move creates awkward situations where zombies fly past humans with both of them missing.

**Part 2**

Now onto the maps themselves; Lets start by comparing the initial spawns of each map.

In Origins, Humans spawn on one side of the room and zombies on the other. The zombies are behind glass, above the humans and must run across the human's immediate line of sight before they can descend upon them. This gives everyone a chance to take in their situation before being thrust into combat and it is designed to give both sides a chance to take each other out. The room is small enough that the zombies have a shot at taking out one or a few humans early if they don't play well but not too small as to be a clusterf*ck slaughterhouse. The zombies also get the advantafe of being capable of jumping down onto the humans, as well as the bit of cover provided by the ledge. Humans are also able to chose weather they want to move immediately to the first hold out or try to take out the alpha zombies immediately and give themselves a better chance of moving out without casulties.

Meanwhile in Survive the Underground, humans spawn in a big open room facing a wall with a slowly opening door, while the zombies spawn in the shadows of a staircase with a softkill barrier. I think you can see where this causes problems in comparison. Humans either get slaughtered as they selfishly scramble over each other to get though the opening door, or they turn around in time to engage the zombies in wildly inconsistent combat with close range weapons which is frustrating for both sides. No tactics whatsoever.
 
Then we get to how each game handles map movement.

Origins' corridors give zombies cover to advance and regroup but is also paced to where humans can play with minimal time with their backs turned to the zombies. It encourages movement by naturally making early areas less hospitable using advancing zombies spawns and playing into other design elements. Zombies at various points also have various methods of approach and sometimes even soft flanking routes, forcing humans to stay on their toes. The best example of this is the first holdout in the map. It appears comfortable at first with access to a turret, a generous helping of ammo and even a couple power weapons (albiet with severely limited ammo) and only one direction that they need to worry about zombies from however after a certain time the zombies get a spawn in an elevator shaft immediately flanking them. This flushes the humans out of the room naturally, and even punishes any "heroes" who try to camp the room for the whole  by opening another flanking path for the zombies that cuts their advance off while leaving them to fight zombies from three directions. (said final flanking path also serves the later parts' encounters as well.

Survive the underground however has encounters that are just bad for both sides. First off the method it uses to move players is to just shut doors on them and then instakill them if they don't make it through. This is best demonstrated in the area directly following  What this does is force humans to sprint with their backs to the zombies, leaving them vulnerable. Then when they get to the closing door there in not enough room for everyone to even make it. Teamwork is outright discouraged and the pacing is destroyed. Meanwhile the zombies have the frustrating task of sprinting down narrow corridors with zero cover whatsoever. This is a problem throughout the entire map but it is at it's worst int the train where zombies must run though a narrow and long corridor with no cover into literal machine gun fire. Even worse this that this map and many others like it have light parkour segments, exacerbating the issues associated with this.
