Join us this Wednesday for the release of our fully arted Skirmish at Darkstar remake during our weekly TSG Warzone play session! The project has been ongoing for nearly two years, and we're finally able to showcase players a full mode and map experience together. #Halo

Just a reminder that Crisp is single handedly making modding Halo Reach, H4, and H2A MP even remotely possible. And then he's going and doing crazy stuff with Blender/mod tools crossovers to do insane stuff like this.

Give this man all the credit.

Happy Halodays, Spartans! 🎄🎁

Putting the ask out there! Would folks be interested if we run a full on double elimination bracket similar to what we did in small capacity for @ExtraLife4Kids ?

It was one of our most popular sections and we could make some pretty cool prizes I think. 👀

[Women of Halo ✨ @WomenofHalo]

If any ladies are interested in playing in ladies swat or snipers customs, let us know!

[Halo @Halo]

To all who served, and those who continue to serve – your sacrifice gives us hope for tomorrow.

Thank you. Today and always. #VeteransDay

A special thanks to our step-ladder, for keeping our stream alive during a major storm in South Carolina.

We ended Extra Life at 10,136.00; all to benefit @ExtraLife4Kids and the kiddos.

Thank you guys so much for ALL your support!

Donations are open through 12/31/2025
