Launch-day post examples for each channel, built from the event page's own facts and the finished key art. Mockup chrome is an approximation, and the engagement numbers in it are furniture, not predictions. The copy blocks are the part to actually use.
Art cuts produced here: vertical 1080x1920 · square 1080x1080 · X card 1200x675. The 16:9 thumbnail and the 8-second WebM already exist in scratch-arms-week-art/export. Seven posters follow the per-platform examples, in the Posters and infographics section. Short link throughout is d2ch.link/MJM5QLS, the event's own, which resolves to the event page.

ARMS WEEK: BLACK ARMORY is live. Seven days. Black Armory weapons only. Five challenges to clear solo and with a fireteam, and every kill the community lands counts toward 1,000,000. Every milestone unlocks an emblem for everyone. d2communityhub.com/events/arms-week-black-armory
The five challenges, Black Armory weapons only: Solo Ops: Creation (solo) Fireteam Ops: The Glassway Pinnacle Ops: Zero Hour Grasp of Avarice Vault of Glass An emblem for each. Clear all five and you earn the badge.
Every Black Armory kill counts toward the community total. 250K, 500K, 750K, 1M. Each one unlocks an emblem for everybody taking part. Top contributors take Diamond, Gold, Silver or Bronze. Everyone who joins in takes Bronze.
Image: use the 8-second WebM rather than the still if you can. Video outperforms a static image here, and it already exists. Fall back to out/xcard.png (1200x675), which is rendered at native size rather than downscaled from the 1920 thumbnail.

We built a community Arms Week for Black Armory: five challenges, and a shared goal of one million kills
Hey all. We run the Destiny 2 Community Hub, a free community site, and this week we are running the first of our Arms Weeks. Each one features a foundry rather than a weapon type, and Black Armory is up first. The idea is simple: put the Forge guns back in your hands for a week and see what the community can do with them together. Five challenges, all Black Armory weapons only: · Solo Ops: Creation (solo) · Fireteam Ops: The Glassway · Pinnacle Ops: Zero Hour · Grasp of Avarice · Vault of Glass Every kill anyone lands with a Black Armory weapon adds to a shared total. At 250K, 500K, 750K and 1M we all unlock an emblem, whether you got one kill or ten thousand. It is free, there is nothing to buy, and it runs until the 22nd.
Link goes in a comment or the very end, never the title. The post has to stand up as a thing worth reading on its own.
A launch post is asking people for something. A milestone post is telling them something happened, which is the kind of thing that gets upvoted rather than removed. If you only get one Reddit post out of this week, spend it here instead.
The community just put 500,000 kills through Black Armory weapons in four days
Quick update from the Arms Week we are running over at the Destiny 2 Community Hub. We set a shared goal of a million Black Armory kills this week. Four days in and we are at 500K, which is halfway with three days still to run. [screenshot of the milestone] Nothing here is paid or locked. Every milestone unlocks an emblem for everyone taking part, whether you contributed one kill or ten thousand, and it ends on the 22nd if anyone wants to pile in for the back half.

Guardians, our first ever Arms Week starts today and the featured foundry is Black Armory. ⚒ For the next seven days, dust off the Forge weapons. There are five challenges to clear, solo and with a fireteam: ✓ Solo Ops: Creation ✓ Fireteam Ops: The Glassway ✓ Pinnacle Ops: Zero Hour ✓ Grasp of Avarice ✓ Vault of Glass Each one earns you an emblem, and clearing all five earns a badge. On top of that, every Black Armory kill the whole community lands counts toward a shared goal of one million. Hit a milestone and everybody taking part gets the emblem, no matter how much you contributed. It is completely free and it runs until 22 September.

Take part: https://d2communityhub.com/events/arms-week-black-armory
Easiest version to actually make: the existing 8-second WebM, held and captioned, is most of a 40-second cut already. The higher-value video is the recap after the 22nd, since the leaderboard and the final kill count are real numbers and need no script.

One week. Black Armory only. One million kills between all of us. #destiny2 #blackarmory #destiny2community #destiny2clips #bungie
Image: out/vertical.png (1080x1920), composed for this specifically. The lockup sits high because TikTok's own UI covers roughly the bottom 320px with the caption and the right 180px with the action rail, so the lower third is left deliberately empty.

@everyone Arms Week is here, and the first featured foundry is Black Armory.

This is your own audience and the cheapest reach you have, so it is the one to post the milestones in as they land, not just the launch.
These carry the information in the image itself, so they still work when someone reposts the picture without the caption. All are 1080x1350 (4:5, the most feed space a single image gets) except the story cut, which is 1080x1920. Every fact on them comes from the event's own API payload: the five challenge names, the four kill milestones, the four placement tiers, the window and the short link.

The single most useful pre-launch post, and it only exists because the event page says so: Black Armory weapons drop from Arena Ops. Anyone who reads this on Monday turns up on Tuesday already able to play.
Arms Week starts Tuesday, and the first featured foundry is Black Armory. Black Armory weapons drop from Arena Ops, so farm some up now. From Tuesday, they are the only guns that count. d2ch.link/MJM5QLS

The one that answers "what do I actually do". Solo is tagged separately from fireteam because that is the first thing anyone wants to know.
Five challenges. Black Armory weapons only. Seven days. Solo Ops: Creation Fireteam Ops: The Glassway Pinnacle Ops: Zero Hour Grasp of Avarice Vault of Glass An emblem for each. Clear all five and you earn the badge. d2ch.link/MJM5QLS

One million Black Armory kills, together. Every kill anyone lands counts toward the total. At 250K, 500K, 750K and 1M, everyone taking part gets an emblem, whether you landed one kill or ten thousand. Just log in and play. d2ch.link/MJM5QLS

Exclusive badges for the biggest hitters this week. Diamond for the top 10. Gold for the top 100. Silver for the top 250. Bronze for everyone who takes part. Turn up at all and you leave with something. d2ch.link/MJM5QLS

The one to pin, and the one to use where a reader will not scroll a thread: the Facebook group, a Reddit post, the Discord announcement.
Everything in Arms Week: Black Armory, on one card. Five challenges, a shared goal of one million kills, and badges for the top contributors. Free, and it runs until the 22nd. d2ch.link/MJM5QLS

This is the shape that earns a Reddit post rather than getting removed as promotion, because it reports something that happened rather than asking for anything.
[520,000] Black Armory kills and counting. That is [two] of four milestones unlocked with [three] days left, and every one of them is an emblem for everyone taking part. d2ch.link/MJM5QLS

The five challenges again at 9:16 for TikTok, Reels and stories. Same caveat as the key art vertical: a still gets very little reach on TikTok on its own. This is worth posting as a story or as the end card of a clip, not as a standalone TikTok.
1080x1920, 16 seconds, H.264 MP4. Text beats through all five challenges over the same forge motion as the site's banner video: rising sparks, the glow breathing, and the star chart drifting slowly behind everything.
It loops seamlessly. 16 seconds is exactly two laps of the 8-second spark cycle, and the text is at zero opacity at both ends, so frame 480 matches frame 0. TikTok replays on loop, so that is free polish. The one exception is the star chart, which rotates continuously and snaps back at the wrap; at 9% opacity behind the wash it is not detectable.
One week. Black Armory only. One million kills between all of us. Five challenges, an emblem for each, and a badge if you clear them all. #destiny2 #blackarmory #destiny2community #bungie #destiny2clips
No audio track, on purpose: TikTok expects you to add a sound in the app. Pick something with a beat around 1.8s per bar and the challenge beats will land roughly on it.
