Ok so in the colony launch trailer at the 33 sec mark the weird animal noise you hear is from the first halo on the the level Guilty Spark. This is the level where The Flood is first introduced.So here is a link to the launch trailer: Halo Wars 2 Colony Launch Trailer - YouTube just copy paste it. put it to the 33 sec mark. Also here is the link to the soundtrack of Guilty Spark: Halo CE Complete Soundtrack 07 - 343 Guilty Spark - YouTube copy paste put it at the 35 sec mark and listen and see how they are the same noise! But who knows if 343 is teasing flood. What do you guys think?

Nice Reference 
Do you know how awesome it would be if suddenly we have a flood Leader.

It would be game changing a whole new faction new units,building designs,leader powers, Horrific and inhumane screeching! 
How do y’all imagine the Flood in HW2?
A whole new faction with its own three leaders? Remember when H2’s Gravemind had the Prophet and Oracle wrapped up in its tentacles? I’d like to have different leaders like that for the Flood faction.
Or just something related to Campaign DLC?
Could we be seeing a completely new species to play as.
