Quick answer (TLDR): Coming back to Warzone in Season 4 (live since June 4, 2026)? Three things changed that you need to know first. (1) The big-map Battle Royale is Avalon; Fortune's Keep is back as a Resurgence map alongside Rebirth Island and Haven's Hollow; and 52v52 Clash runs on Verdansk. (2) Warzone is one free download tied to Black Ops 7 — you don't buy anything to play. (3) PC players must have TPM 2.0 + Secure Boot enabled or you're locked to Battle Royale Casual only. The fastest way to catch up: warm up in Battle Royale Casual (it has bots), grind contracts + 2XP to re-level your guns, then move to ranked. Full roadmap below.
If the last Warzone you played was on Verdansk or Al Mazrah, dropping back in for Season 4 is disorienting — new map, new movement, a security check at the door, and a battle pass you're 90 tiers behind on. This guide is the no-fluff catch-up: exactly what changed, which version to install, why you might be stuck in Casual, and the fastest path back to competitive. Every fact here is checked against the official Call of Duty Season 04 patch notes.
Which version of Warzone do I download in 2026?
Just one: Call of Duty: Warzone, and it's free. There is no "Warzone 2" or separate Warzone app anymore — the standalone free-to-play client is the current game, now integrated with Black Ops 7 content. You do not need to own Black Ops 7 to play Warzone, although owning BO7 gives you a shared progression and an earlier head start on weapon unlocks.
A few install gotchas for returning players:
- Delete old data packs. Warzone shares files with the premium titles; if you still have a multi-hundred-GB legacy install, uninstall unused campaign/multiplayer/Zombies data packs to reclaim space before patching.
- One account, one progression. Sign into the same Activision/Call of Duty account you used before — your old operators, blueprints, and store purchases are tied to it.
- PC: check your security settings first (see the attestation section below) so you don't finish a 100GB download only to get locked out of the main playlists.
What changed in Warzone since you last played? (Season 4 recap)
Season 4 is a big content drop across maps, movement, and modes. Here's the returning-player version:
| Area | What's live in Season 4 |
|---|---|
| Battle Royale map | Avalon — Buy Stations increased to 64 (up from 49) for far better map coverage |
| Resurgence maps | Fortune's Keep (returned + refreshed), Rebirth Island, Haven's Hollow |
| Large-team mode | 52v52 Clash on Verdansk — endless respawns, capture objectives, contracts, vehicles |
| New to Warzone | Gun Game arrives in Warzone for the first time on Resurgence maps |
| Movement | Grappling Hook and Wall Jump traversal featured in modes like Clash; ziplines/ascenders across POIs |
| Progression | Placement Challenges — earn Placement Points by hitting placement milestones across BR, Resurgence and Casual |
| Live event | Illicit Cargo Camo Event — unlock the VX Compact Assault Rifle and remastered Black Ops III camos |
The headline for returning players is Fortune's Keep. As the patch notes put it:
"Fortune's Keep returns! Revisit familiar locations while exploring new points of interest and updated pathways that introduce additional depth to engagements throughout the map."
— Call of Duty: Warzone Season 04 Patch Notes
Classic POIs (Keep, Winery, Town, Pier, Lighthouse, Overlook, Graveyard, Grotto, Smuggler's Cove) are all still there, with new micro-POIs like the Sea Science Aquatic Laboratory at Bay and Capt. Bubby's Chum Haus between Pier and Lighthouse. If you have muscle memory for the old island, most of it still applies.
What are all the current Warzone maps in Season 4?
There are three map "buckets" running right now, and which one you queue into changes the whole pace of the game:
- Battle Royale (Avalon) — the full-size battle royale (up to 150 players). Slowest to re-learn, biggest payoff. The jump from 49 to 64 Buy Stations means you're far less likely to land in a dead quadrant with no station nearby.
- Resurgence (Fortune's Keep / Rebirth Island / Haven's Hollow) — smaller, faster, with respawns while a teammate is alive. This is the best mode to rebuild your skills — more gunfights per minute, lower punishment for dying. Ranked Resurgence rotates through these maps.
- Clash (Verdansk, 52v52) — chaotic, respawn-heavy, objective-based. Zero pressure, pure gunplay practice. Great for re-learning recoil and testing weapons without losing a whole match to one death.
If you've been away a long time, start in Resurgence or Clash, not full BR. You'll get more reps and re-learn the new movement faster.
Why am I locked to Battle Royale Casual? (The attestation requirement)
This is the single most common "I came back and can't play" problem on PC. Since the security update, Call of Duty validates your hardware through Microsoft Azure Attestation (MAA), and failing it quarantines you into a restricted playlist. Straight from the official patch notes:
"Players who do not complete attestation will be limited to Nuketown 24/7 in Call of Duty: Black Ops 7 and Battle Royale Casual in Call of Duty: Warzone."
— Call of Duty: Warzone Season 04 Patch Notes
To access all playlists (ranked, full BR, Resurgence, Clash) your PC needs:
- TPM 2.0 (Trusted Platform Module) enabled in BIOS
- Secure Boot enabled in BIOS
A frustrating catch for AMD users: even with both enabled, some AMD fTPM software in the 3.x.0.x range returns an attestation error, and the fix is a BIOS/firmware update — not another toggle. If you're stuck on this exact wall, we've already written the full walkthroughs:
- Warzone & Black Ops 7 'Failed Attestation Status' Fix: Enable TPM 2.0, Secure Boot & Update BIOS — the base fix, enable everything correctly.
- 'BIOS Update Required' Still Showing With TPM 2.0 & Secure Boot On? Advanced Attestation Fixes — for the stubborn cases where the basics aren't enough (fTPM version, cheap boards, VMs).
Here's the silver lining: Battle Royale Casual is genuinely useful to a returning player — which is the next section.
How do I catch up fast as a returning player?
You're behind on weapon levels, battle pass tiers, and reflexes. Here's the efficient order of operations.
1. Warm up in Battle Royale Casual. Casual queues are softer and seeded with bots, so you can land, loot, and win gunfights without instantly running into a stacked squad. Returning players on Reddit say the same thing — drop into Casual to shoot bots and rank up before touching the sweaty normal queues. Use this to re-learn the map and movement at low risk. (If this is the only mode you can access, see the attestation section above.)
2. Farm contracts + 2XP for weapon levels. Your guns reset their attachment grind every era. Running contracts (Bounty, Recon, Scavenger) stacks XP fast, and Activision regularly runs Double XP / Double Weapon XP windows — stack your sessions on those days. Low-skill, low-pressure lobbies are the fastest, calmest way to take a fresh weapon all the way to its full attachment list.
3. Chase Placement Challenges. The new Placement Points system rewards consistent finishes across BR, Resurgence and Casual — so even mediocre placements compound into rewards while you're rusty.
4. Re-equip what you already own (most people miss this — see the "stuff still locked" section below).
If you'd rather skip the multi-week grind entirely — re-level your weapons, hit a rank, or get warmed up in genuinely easy lobbies — that's exactly what we do:
Get back into Warzone the fast way:
>
- CoD Bot Lobbies — easy lobbies to relearn the game and level weapons fast
- CoD Account & Weapon Leveling — skip the grind, catch up on unlocks
- Warzone Ranked Boost — climb the SR ladder without the rust tax
Why is my stuff still locked at max level?
A very common returning-player complaint: you hit (or already had) max account level, but weapons, operators, or attachments still show as locked. Two things are usually going on:
- It's unlocked but not equipped. Go to Career > Progress (or the Weapons/Operator menus) and look for items marked as unlocked — you have to manually equip them. Many "locked" items are simply sitting unclaimed.
- It's a separate progression track. Weapon levels, Armory/Prestige unlocks, battle pass items, and event rewards are all tracked independently of your account level. Maxing your account doesn't auto-unlock every gun — each weapon still has its own attachment grind, and some attachments are gated behind Prestige/Armory tasks.
If you came over from Black Ops 7's progression, our BO7 Armory Unlocks guide explains how the shared unlock system works and how to claim missed weapons fast.
Returning player catch-up roadmap
| Step | Do this | Why |
|---|---|---|
| 1 | Install free Warzone, sign into your old account | Recover operators, blueprints, purchases |
| 2 | PC: enable TPM 2.0 + Secure Boot | Avoid the Battle Royale Casual lockout |
| 3 | Play Resurgence / Clash first | Most gunfights per minute = fastest skill rebuild |
| 4 | Farm contracts on 2XP days | Re-level weapons and battle pass fast |
| 5 | Check Career > Progress and equip unlocks | Stop fighting with locked-feeling loadouts |
| 6 | Move to full BR / Ranked when warmed up | Compete once your aim and map knowledge are back |
FAQ
Is Warzone free in 2026? Yes. Call of Duty: Warzone is free-to-play and is the only current Warzone client. You don't need to buy Black Ops 7 to play it, though owning BO7 shares progression and gives you a faster start on unlocks.
Which Warzone do I download — there are so many options? Just install Call of Duty: Warzone (the free title). There's no separate "Warzone 2" app anymore; the current free client is integrated with Black Ops 7. Sign in with your existing Activision account to restore your old content.
Why can I only play Battle Royale Casual? Your PC failed the Microsoft Azure Attestation security check. Enable TPM 2.0 and Secure Boot in BIOS to unlock all playlists; AMD users may also need a BIOS/firmware update if their fTPM version is in the 3.x.0.x range. See our attestation fix guide.
What's the fastest way to level my weapons after coming back? Run contracts during Double XP / Double Weapon XP events, and use easy/Casual lobbies to complete the attachment grind with low risk. This is the lowest-stress path from a fresh weapon to a fully kitted one.
Where did Verdansk and Fortune's Keep go — are the old maps back? Fortune's Keep is back as a refreshed Resurgence map, and Verdansk hosts the 52v52 Clash mode. The current big-map Battle Royale is Avalon, with Rebirth Island and Haven's Hollow rounding out Resurgence.
My account is max level but everything is still locked — why? Account level is separate from weapon levels and Armory/Prestige unlocks. Check Career > Progress, equip anything already unlocked, and remember each weapon has its own attachment grind regardless of your account level.
