Although, I am curious as to how the waves of Flood will start at each round and if we will get any Flood vehicles. Overall, little is known about this update, but it is safe to say that the overall game mode will likely be unaffected since it would already suit the Flood well. The map does appear to be a standard ODST setting and might be an existing map or a new map created from the New Mombasato area (unless the Flood decided to decorate their hives with palm trees).

They may be a selectable enemy for any map/mode, but the screenshot shows an area that is very dark and could very likely be a new map that is just focused on the Flood. Since it is just a teaser image, we do not know what other changes are coming to firefight or how the Flood will be added. Firefight was oddly one of the few horde-style games that did not feature some form of a zombie or undead enemy, which was even odder when you think of the fact Halo has the exact enemy needed for this to happen already. 1-16 of 61 results for 'halo the flood' Halo: The Flood (2) Part of: Halo Universe (19 Books) by William C. Dietz, this novel appeared on the Publishers Weekly bestsellers list during May 2003.

Well, 12 years after ODST was released, 343 has announced that the Flood is coming to Halo 3: ODST’s firefight mode! This was spotted in a teaser image on 343’s latest forum post and the hype is real. The following novel, entitled Halo: The Flood, is a tie-in to Halo: Combat Evolved, describing not only the experiences of the Master Chief but also those of other characters on Installation 04. Halo 1 and 3 have been added to the custom game browser. ODST’s setting did not include the Flood, so it was not surprising to see them missing from the mode, but the fact that ODST soldiers did directly fight the Flood in other Halo games and the Flood did land on Earth during Halo 3 (after the events of ODST), it was not hard to see the players wanting the Flood. Having fixed the first game's visual bugs, Halo 1 will now let you use a HUD more faithful to the original design (upscaled to 4K resolutions). Halo 3: ODST gave us one of the most unique Halo game modes in the series, Firefight, and with this mode came an endless amount of community support to fight against the Flood.
