Alright, let me start off by saying that I really love the new infection mode, I was a little iffy about the the AR start, and weapons on the map, but it actually works great. However, one thing I feel that infection should have is vehicle options (boarding, driving, gunning) for the infected, and players. This would allow a wider range of possibilities in custom games.
Now, I have another one that does not pertain to gameplay, but more so has to do with aesthetics. I feel that we should have forced colours for the infected (and survivors) as well as the ability to change the armour effect, so instead of the pestilence we could give them the speedboost glow, or the the damage boost flames. Honestly this part is more so to heighten the immersion of certain maps (I might be a little biased towards this because of one of the maps I’m making).
These are my requests for infection, you of course can discuss what you would like to see added in, and hopefully some of that stuff will be added soon.
