Will there be a console version of Combat One - Annihilator?

Yes

Combat One - Annihilator is planned to be released on Next-Gen Consoles including Xbox One Series S/X and PlayStation 5 at a later time.
The game will feature full Crossplay Support which can be enabled/disabled. 

We anticipate console release along side a major Season Pack Update but do not have any concrete release dates at this time.
