ISO Nightshade Rush

Quick Fix

Faster health recovery, rewarding you for chaining fights.

Blood Rush

Grants Tactical Sprint — at launch it's the only way to get it, and it triggers automatically when you sprint (toggle in Movement settings).

Battle Hardened

Strongly resists Flash, Concussion and Screamer Mine effects.

Flash Grenade

Blinds and deafens enemies — the best room-clearing tactical (range and duration slightly reduced at launch).

Frag Grenade

Cookable grenade — clears corners and objectives.

Portable Radar

Pings nearby enemies on the minimap for your team.

UAV

4 kills

Reveals enemies on the minimap for your team. Tougher to shoot down since launch.

Crossfire

6 kills

New for MW4 — full in-game details coming soon.

Attack Helicopter

10 kills

Autonomous gunship that hunts enemies.
