The complete official 10-streak Multiplayer Beta roster with latest documented costs and separately labelled earlier screenshot evidence.
BETA VS LAUNCH CONTEXT
How many Killstreaks are in MW4?
10 available in the Multiplayer Beta. The broader Modern Warfare 4 Multiplayer arsenal has 17 Killstreaks announced overall. Additional streaks arrive at launch. The other seven are not named or documented well enough here, so we do not publish guessed entities, costs or thin placeholder pages.
A Player Level unlock controls when a reward becomes selectable. The in-match Killstreak cost is the number of eliminations needed to earn it during a match; these are different values. The latest documented/earlier cost pairs below remain limited to the four rewards whose evidence is traceable.
Modern Warfare 4 uses elimination streaks rather than scorestreaks in this Beta. Players can equip up to three rewards, and the official guide says the roster spans requirements of 3, 5, 7, 9 or 11 consecutive eliminations. Unlock level and in-match streak cost are different values: Player Level controls when a reward becomes selectable, while eliminations determine when it can be earned during a match.
The publisher visual introduces the Beta Killstreak system. The table below carries the official roster and unlock levels; the separate gameplay capture is used only for costs visible in that menu.
