Fast Zombies - Big Horde Edition (Mutation)

Work in progress. This is a coop mutation designed to be played on Advanced difficulty that greatly increases the speed of common infected, as well as boomers and chargers (slightly), while also adding increased horde sizes and shorter times between them. If you die, you'll restart the next map with 80 HP instead of 50. Specials spawn a little bit more quickly and seem to be slightly more dangerous even though they do standard damage. Everything else is default, so you don't get any buffer room with weapon strength, ammo capacity, health, or anything like that. Implemented using some of GLOCK's Fast Infected Hordes scripts. This mutation is difficult yet balanced for Advanced difficulty. It may feel unfair or unbalanced on Expert.

Details: Common infected run about four times faster than normal but their health and damage output are unchanged. Additionally, their climbing and attack animations can't be changed without physically altering their animations, so they're as slow as usual if they have to climb to reach you and when they reach to attack. No health or damage handicaps are in effect, so you won't die in one hit or die after going down once. In fact, I've added a number of things to make the mutation slightly easier. Bots will react more quickly when someone is pinned, and dead players will respawn with 80 HP instead of 50. While this doesn't seem like a big change, what it means is bots who respawn shouldn't instantly use up their medkits in the saferoom on the next map. Unlike a lot of other mutations that artificially ramp up the difficulty by giving you huge penalties or handicaps from getting hit, this changes nothing integral about the core game mechanics, it only makes you to deal with a lot more common infected and forces you to think quickly about how to deal with special infected and rescue your teammates while under attack.

This mutation has some pretty interesting consequences. For starters, this actually makes throwables and gas cans useful, and it makes resource scavenging more important than before. In certain instances a well-placed gas can or well-timed pipe bomb can save the team. This also makes alarm cars an actual threat, and I imagine the alarm car segment of The Parish can be a nightmare on Expert difficulty. The lowered special respawn rate is negligible; if I didn't lower the rate, it would be absolutely ridiculous how long it would take for special infected to respawn and it would be too easy. The way it is currently is very challenging but by no means impossible. Melee weapons are highly recommended. As with every mutation, it is important to play this with as many human players as possible.

As always, feedback is much appreciated. I may consider making a Realism version if there is any desire for it.

*Bugs: Bots seem to be a little bugged when trying to deal with infected behind them. I'm not sure why this is but sometimes they'll just attack the commons in front of them and will just refuse to turn around, so you'll have to babysit them a bit. I'll look into trying to fix it. Also, boomers and chargers will move faster than their animations allow so it'll just look like their skating around. I can't change this, unfortunately.
