Discovered some new Halo listings on Amazon. Obviously out of stock and without pics (for now).
Heroes wave 9. Captain Keyes. Jorge. Elite Sesa Refumee. ODST Graves. Spartan Warmaster. Spartan Soldier.
ODST Flood Hunter drop pod. With flamethrower and flame effect. Flood splatter deco.
ODST Guillotine drop pod. No other info to distinguish it from other drop pods.
Fireteam Spartan vs Elite Rangers. Two of each. With flight stands for Rangers.
Fireteam ODST vs Banished Brutes. Also has buildable Banished Turret.
Metallic Green Playset. No other useful info to determine what this is.
So it seems like future (or at least these two) Fireteams might switch to two opposing forces instead of all four figures being from one side.
