"The free DLC initiative for Halo 5: Guardians continues this month with an expansion called Hammer Storm. It features a new Arena map, new game modes (including Grifball), more weapons, additional Reqs, and further character customization options. Develop"
The new modes are Halo fan-favorite Grifball and Assault. 343 has made some big changes to Grifball since the last time we saw it, and you can get a full rundown of the new version here in our previous coverage. Additionally, the update will allow you to create custom gametypes including Oddball and Ricochet, while Fiesta Slayer is also making a comeback.
Hammer Storm's new map is the epic-looking Torque. Only one piece of concept art has been released for it, and you can see it above. It looks like Torque is set on a space station.
Additionally, the update comes with new armor sets (Decimator and Marauder), as well as the Gravity Hammer melee weapon, among other new items. You can see some of the new Reqs in the image gallery below, but most are blurred out for now.
343 will showcase the first Torque gameplay and talk more about Hammer Storm overall during a video broadcast that is scheduled to take place on February 26.
