MW4 Killstreaks: All 17, Kill Costs and Unlock Levels

Modern Warfare 4 launched on 23 October 2026 with 17 Killstreaks, and every one of them unlocks through your Multiplayer player level, from Level 4 to Level 55. Activision’s launch post of 19 October gives each streak a kill cost and an unlock level. The launch patch notes of 21 October add two tuning changes and one number that does not match the post: the cost of the UAV.

Kill costs and unlock levels below are from Activision’s launch post. Create-a-Class opens at Player Level 4; before that you play premade Default Loadouts, and whether those carry Killstreaks is not stated. Hardline, a Perk 2 option unlocked at Level 4, cuts every Killstreak cost by one kill. Objective play also fills the Killstreak meter, though kills still count for the most.

All 17 unlock levels now come from Activision’s own table, including the seven above Level 30 that the beta could not reach. The descriptions are short paraphrases of the official ones. Damage, radius and duration are not published, so this table does not rank the streaks.

Activision’s two launch documents disagree on the UAV. The launch post of 19 October puts it in the 4-kill group with Bomb Glider, Care Package and Impact Warhead. The launch patch notes of 21 October say the cost rise from the second beta weekend stays for launch, which they say makes the UAV 5 kills, or 4 with Hardline.

We print both, because neither document says which one is wrong. The patch notes give no figure for the other 16 streaks, so their costs in the table come from the launch post alone. Before you build a loadout around a cheap UAV, open Create-a-Class and read its cost with and without Hardline.

Beta history, in short: the second beta weekend raised the cost of every Killstreak by one kill, and Hardline took one off again. That is why lists written during the first weekend show lower numbers.

UAV, Artillery Beacon and Attack Helicopter unlock at Player Level 4, the level that opens Create-a-Class, one in each of the 4-, 6- and 10-kill groups. Bomb Glider follows at Level 6 and Care Package at Level 9. The first 8-kill streak, Wheelson, arrives at Level 16.

Activision’s launch post lists 17 Killstreaks, and a Tactical Nuke is not one of them. Neither launch document gives a Nuke a kill count, an unlock level or rules. The only official trace is one audio fix in the launch patch notes that mentions the Nuke sequence. Players reported a nuke during the beta, but Activision has not documented it, so we make no claim about how it works at launch.

Each Custom Loadout carries its own Killstreaks, so changing class changes your streaks with it. The patch notes call this a first for a Modern Warfare game. Kill Chain, a Perk 1 option at Level 48, makes kills by your Killstreaks award half streak points. We covered Create-a-Class and all 18 perks in MW4 Perks and Create-a-Class, and how objective play fills the meter in MW4 Smartstreaks.

Ten Killstreaks are unlocked by Level 26. The other seven unlock between Level 31 and Level 55, so the full set, including both 12-kill streaks, needs the top of the 1–55 player-level range.

If you would rather not make that climb yourself, our MW4 Rank Leveling raises your rank to the level you name, played by hand on your account. The weapons, perks and Killstreaks behind those levels unlock along the way.
