Flood Firefight & Credit system

This is one of my dreams that I hope will happen in Halo Infinite. A firefight mode like we had in ODST, where we can choose our enemies. Covenant, Prometheans or Flood. To have a firefight mode with all kinds of flood coming at you, like the juggernaut floods in Halo 2 and Halo Wars 2 as a boss fight.
I also think it would be awesome to have the credit system as we had in reach but we have this collection system as in H5. Once you buy a H2 Battle rifle or HCE magnum, you will have it permanently and you can start with it in the Flood firefight. We can buy all kinds of stuff like we had in H5 just without all the unnesscessary variants. A needlerwarthog would be awesome to use and I would also love to have the sticky detonator and the flamethrower in a Flood firefight. I think that it would be best if we only could buy the precision weapons but the power weapons would be placed in the maps. It would also be spectacular to revive or re-use old classic iconic flood based maps for this mode. Like ‘Cortana’, ‘Keyes’, ‘The Maw’, ‘The library’, ‘Quarantine Zone’ and others. If we are really lucky and we get the classic art style, guns (I really want the HCE shotgun), flood, brutes, music and the feeling of Halo, then this would be awesome. I really hope we get long missions with beautiful landscapes as we got in the original trilogy. The trailer gave me everything I wished for so far, so this is going to be hype!
What are your wishes for Halo Infinite?

I’ve always wanted a Flood style Firefight mode. Something like Firefight, but scary and hard.
