Files for Infection medals were recently found in Infinite, so it’s likely the mode exists or was in development. Why isn’t it in the game? Here’s the reality. Every map is really only good for maybe 1 or 2 modes, and are borderline incompatible with others. Some might pass with Infection, but only in specific defendable areas.
Some examples
Aquarius:
Good for CTF and Slayer
Could maybe pass for Oddball
Probably awful for Strongholds and Infection
Live Fire:
Good for Slayer and Strongholds
Works alright for Oddball
Probably awful for CTF
Might pass for Infection
Recharge:
Good for Slayer and Strongholds
Mostly fine for Oddball
Probably awful for CTF
Actually passable for Infection in some parts of the map
Streets:
Good for Slayer, Strongholds, and Oddball
Probably great for Infection
Not good for CTF
Bazaar:
Good for CTF and Slayer
Might be alright for Oddball and Strongholds
Would probably be awful for Infection if everyone defends from one flag area
Launch Site:
Only good for One Flag
Passable for Slayer
Likely awful for Strongholds and unplayable for Two Flag CTF
The back room on the man cannon side would always be the camping room for Oddball and Infection and would suck
Behemoth:
Decent for CTF and Slayer
Way too open for Strongholds, Oddball, and Infection
It’s just not as good as Sandtrap was
The maps just are not properly designed to accommodate all game modes and future game modes, similarly to how BTB maps are too claustrophobic and poorly designed for driving vehicles. If we get Infection, I hope it comes with 2 new maps designed for Infection.
Also there’s the whole Bulldog/Sidekick thing, and Swords not having no clash damage and melee stun blocking.
