Infection, a multiplayer mode introduced to the Halo series with Halo 3, later returning in 2010's Halo: Reach, may come back to the franchise through an update to Halo: The Master Chief Collection, if a teaser in 343 Industries' latest update is any indication.
"The playlist team continues to work on future updates," 343 wrote, "and its quite likely that we'll be talking more about things like Infection in the coming weeks."
In Infection, the number of "survivor" players is whittled down by kills from "infected" players until only one is remaining, who gets the honor of "Last Man Standing." The mode was modeled on a custom gametype players developed themselves for Halo 2. The mode was altered and renamed "Flood: in 2012's Halo 4.
Halo: The Master Chief Collection comprises all of the numbered editions of the franchise and is available on Xbox One. Halo 5: Guardians will launch at the end of October for the same console.
"The Halo 5 team is busy putting the finishing touches on new experiences - some of which you've seen glimpses of, and many of which you have not," 343 added in its update. "here are exciting new battlegrounds being built, weapons being tweaked, tuned, and skinned, and plenty more that we are looking forward to sharing with you in the coming months.." More news is expected out of Gamescom, which begins this week.
