what if, through the infection customs settings, we could change what slyer model the infected players use. such infection models would be your normal spartan, elites, and flood infected spartans (H2A, for example). this would be helpful for making new custom game modes.
one such game mode is a mix of invasion and infection, where it would play out like the standard match of invasion but when players die they become an elite (or spartan, depends on which is the invading team)
