Let’s call the leader ‘The Gravemind’.
OPTION 1
Make it half banished half UNSC.

Infected Generator (flood tentacles are spinning the fan blades instead of the wind)
Infected Banished main base (because it seems there are more crevices that flood matter can squeeze into)
Infected Armory
Infected Raid Camp
Infected Airpad
Infected Foundry
Infected UNSC minibase
Units:
Infected Banished Main base:
Combat form squad (replacing grunts)
Infection form swarm (replacing chopper, able to convert enemy infantry)
Infected Raid camp:
Infected jump pack brutes
Carrier flood form (replacing suicide grunts, can convert enemy infantry to join your team)
Ranged form (replacing elite rangers)
Tank form (replacing hunters)
Infected Foundry:
Infected Marauder
Infected Reaver
Flood Spitter (artillery, spits globs of acid at enemies, replaces kodiak)
Infected Scorpion
Infected Airpad:
Bloaters (replacing engineers, shield ability replaced with self-repair ability)
Flood Swarm (replacing banshee, shoots balls of acid at enemies, from HW1)
Spore cloud (replacing shroud)
Infected Vulture
Infected Armory:
Proto-Gravemind (Hero unit, gives units around it siphoning abilities. It will be dragged along the ground by tank forms)
Infected Condor
OPTION 2
Make a completely new flood faction.
Buildings:
Flood Root (Supply Pad)
Flood Verdure (Generator)
Hive (Main Base)
Cranium (Armory)
Spawn Pit (Barracks)
Swarm Nest (Airpad)
Plague Den (Garage)
Flood Lair (Minibase)
Flood Launcher (Turret; Anti-air upgrade is a goop launcher, Anti-vehicle upgrade is a acid launcher, Anti-Infantry upgrade is a spore launcher)
Units:
The Hive (Main Base):
Combat form squad (replacing grunts)
Infection form swarm (replacing chopper, able to convert enemy infantry)
Blob (meat shields, high health, very low damage like marauders. simply looks like a blob of flood mass with some tentacles)
Spawn Pit (barracks):
Flood Thrasher (shown in halo wars 1. Anti-building, like Goliaths)
Carrier flood form (much like suicide grunts, but can convert enemy infantry to join your team)
Ranged form (anti-infantry)
Tank form (anti-vehicle)
Plague Den (garage):
Flood Worm (unable to attack conventionally. However, it has a fast-recharging y-ability to dig underground and bash enemies from underground)
Flood Spider (anti-air, shoots web-like goop at air that stuns them and damages them over time)
Flood Spitter (artillery, spits globs of acid at enemies that deal damage over time)
Flood Transporter (non-combative, releases 8 infection form swarms upon death and covers enemies in acid, dealing damage over time)
Swarm Nest (airpad):
Bloaters (Similar to engineers, shield ability replaced with self-repair ability)
Flood Swarm (Core Air, shoots balls of acid at enemies, from HW1)
Spore cloud (Similar to shroud/nightingale. Y-ability drops a green fog that only flood (and detecting units) can see through)
Cranium (armory):
Proto-Gravemind (Hero unit, gives units around it siphoning abilities. It will be dragged along the ground by tank forms)
Flood Leviathan (The flood super unit. A massive, hovering, squid-like floating flood form with a bloated head that shoots acid blobs. It’s y-ability is to devour an enemy unit, instantly killing it, but this does not apply to other ultimate units.)
Leader powers:
Tier 1:
Flood dispersal pods (drops 5 infection form swarms into battle, upgrade makes it 8 infection swarms)
Famine (recycle infantry units for resources/population)
Tier 2:
Spore pods (set up spore pods that detonate on proximity to enemy units, upgrade increases no. of pods and no. of infection forms per pod)
Accelerated growth (decreases build time for infantry by 40%, upgrade decreases build time for structures and non-infantry units by 15%)
Tier 3:
Plague (set an area of effect where enemy units take damage and are unable to see, upgrade increases damage and AOE)
Tendril Lock (tentacles shoot out of the ground and disable vehicles, upgrade disables infantry and aircraft as well)
Tier 4:
Self-repair (all infantry constantly heal themselves, upgrade will increase healing rate)
Mechanical Carriers (all vehicles release infection forms once destroyed)
Tier 5:
Hostile Takeover (take over/infect bases that are below 15% health)
The Gravemind (summon the gravemind for 30 seconds to massacre the enemy team)
