A Hawk is not from Halo 3 it is from the game Halo Wars which is not associated with Bungie. Halo Wars Ensemble Studios created the Hawk. You may be thinking of the Hornet or Pelican.
Ensemble Studios created Halo Wars under the direction of 343 Industries and Bungie.
Halo Reach, Halo: Combat Evolved, Halo 2, Halo 3: ODST, and Halo 3 were made by Bungie; Halo: Wars was created by Ensemble Studios; Halo: Combat Evolved Anniversary and Halo 4 were created by 343 Interactive
Halo Wars
From what I know, there is no Halo Wars on the PC.
Halo Wars happened in 2009.
Halo Wars was made in 2009, along with Halo 3 ODST
Do you mean "Where is"? A game like halo wars is called Halo.
No. Halo Combat Evolved happened about 20 years after the events of Halo Wars.
Actually, I don't think there will BE a Halo Wars 2. There's Halo: ODST and Halo: Reach. Those came after Halo Wars (correct me if I'm wrong).
