Two weekends, five maps, a campaign mission you can actually play early, and a full Warzone drop before launch — is that really all packed into one beta? Yes, and this guide breaks down exactly what's live on which weekend, how progression works, and why your beta rank won't carry into October. If you're deciding whether to grind early access or wait for open beta, here's everything you need to plan your weekend.
Weekend One vs. Weekend Two: What's Actually the Difference?
The early access beta runs August 21–25, gated behind a code from pre-order, giveaway, or a generous friend. It launches right as Call of Duty Next wraps up, at 11:00 a.m. Pacific on Xbox Series X|S, PS5, and PC (Battle.net, Steam, Microsoft Store). No last-gen consoles this cycle — that era is officially over.
The open beta runs August 28–September 1, free for anyone, no code required, starting 10:00 a.m. Pacific. It adds Nintendo Switch 2 to the platform list and unlocks Ground War plus Warzone content that weekend one doesn't have.
Feature | Early Access (Aug 21–25) | Open Beta (Aug 28–Sept 1) |
Access | Code required | Free for everyone |
Platforms | Xbox, PS5, PC | Xbox, PS5, PC, Switch 2 |
6v6 Maps | 5 maps | Same 5 maps |
Kill Block | Yes | Yes |
Ground War | No | Combat Outpost, Imjin Farm Land, Wolf Stadium |
Warzone | No | Zodiac Resurgence map |
Campaign Mission | "Entrenched" | "Entrenched" |
Who this matters for: Anyone weighing a pre-order purely for beta access should know weekend two hands out strictly more content for free — so unless you want the head start, patience pays off, especially when you can jump into cheap CoD Modern Warfare 4 Bot Lobbies to practice maps, test classes, and get comfortable with the movement system without spending a dime on early access.
Maps, Modes, and Kill Block Chaos
Weekend One's 6v6 roster covers Rooftops, Silk Worm, Transit 213, Cash Head, and Lotus, playable across TDM, Domination, Hardpoint, Kill Confirmed, the new Inflation mode, and Search and Destroy. Kill Block adds so many map/mode combinations that back-to-back matches rarely repeat, plus exclusive 10v10 and 3v3 Gun Fight variants. A standalone mobility course also lets you test the overhauled movement system — a real departure from BO6/BO7 and Warzone's omni-movement — without the pressure of a live match. For those looking to sharpen their aim or experiment with loadouts, dedicated CoD Modern Warfare 4 Bot Lobbies offer full access to the same maps and modes against AI opposition, making them the perfect low-stakes complement to the high-octane live queues.
Who this matters for: movement-focused players and mode hoppers get the most value here, since the sandbox is deliberately built for experimentation before launch balancing locks things in.
Progression, Rewards, and the Twitch Drops Nobody Should Skip
Everyone starts at level one with a cap around level 30 and up to 19 unlockable weapons. Milestone rewards trigger at specific levels — emblem at 4, charm at 8, weapon sticker at 12, calling card at 16, operator skin at 20, spray at 23, loading screen at 26, and a weapon blueprint at 30. Crucially, these cosmetic rewards carry over to the October 23 launch even though your rank does not. Watching Call of Duty Next or beta streams also earns Twitch drops, and hidden Dark Ops-style challenges are tucked in for extra charms and blueprints.
Who this matters to: completionists chasing cosmetics should prioritize hitting every milestone tier now, since that's the only progress that carries over to the full release.
Quick Tips Before You Drop In
· Save serious grinding for weekend two if you don't have a code — it's the same core content plus Ground War and Warzone.
· Progress carries between weekend one and two, so early hours aren't wasted; just don't expect them at launch.
· Use the mobility course first if you're coming from BO6 or BO7 — the movement system genuinely plays differently.
· Keep an eye on patches during the August 25–28 downtime; balance changes based on weekend one feedback are likely.
