A new Big Team Battle mode has arrived in Halo Infinite. Introducing BTB: Sentry Defense!

Adjutant Resolution, one of Zeta Halo’s submonitors who you met and fought in Halo Infinite’s campaign, has decided to jump into some multiplayer action. Two of them—simply known as “sentries” in this context—are on each team; your objective is to protect your sentries and destroy the enemy’s.

Each team has 2,000 points. As damage is dealt to your sentries, the available score drops, and if you reach 0 it’s game over. Each map will have at least one Repair Field that spawns in a neutral location—in addition to providing health regeneration for your fellow Spartans and vehicles, it’ll also repair your sentries.

BTB: Sentry Defense will be playable on:

• Fragmentation
• Highpower
• Deadlock
• Oasis
• Scarr
• Command

Available this summer!

Tom Warren originally reported it here, however the full article is behind a paywall.

It basically says that "classic style gameplay" doesn't work for the franchise because of the lowering player numbers and "feedback from Reddit". That's already enough to claim it's bs.

"Anything Halo Infinite has done will be ignored and Halo 5 is the blueprint that Project Halo 7 (tentative title) will be built on." Mmm yes let's build a game based on H5, the one that was received so poorly it caused them to go back to classic styled.

All abilities from H5 will be back and includes double jump and wall running. Come on, you're just taking ideas from Titanfall.

This bit is the icing on the cake. "The goal of the campaign's story is to be "the true Halo 6" after the nonsense that was Halo Infinite." I find it hard to believe that someone would think that Infinite was more nonsense than 5.

Rest of it is just prometheans returning but nerfed and no banished but from the first point you can tell this is bs, I just felt like sharing it
