Halo 4 is getting a fresh new matchmaking update today that introduces an exciting new game mode 343 Industries likes to call Ninja Assassins.

“We’ve been playtesting the game type over the past few weeks, and it requires stealth, precision, patience, and a whole lotta Thrustin’,” writes Halo Community Manager Andy “Bravo” Dudynksy in the latest Halo Waypoint update. But what could that possibly mean?

According to Dudynsky, Ninja Assassins is an 8-player Free-for-All game type where Spartans suit up in custom armor and equip themselves with Energy Swords, Sniper Rifles, and Thruster Packs. Ten points are awarded per kill, but a successful assassination will earn you a total of 30 points – equal to three kills. Motion tracker is disabled.

Throughout the match, Spartans level up by scoring kills in succession. There are three tiers, meaning scoring your third kill in one life will boost you up to level three. Here’s the breakdown of each level:

Ninja Level 1

• Shields recharge at a faster rate (2x)
• Assassinations performed at a faster rate (2x)

Ninja Level 2

• Shields recharge at a faster rate (2x)
• Shields recharge sooner than normal (after 3 seconds)
• Assassinations performed at a faster rate (3x)

Ninja Level 3

• Shields recharge at a faster rate (2x)
• Shields recharge sooner than normal (after 2 seconds)
• Assassinations performed at a faster rate (4x)
• Unlimited Thruster Pack energy

Ninja Assassins will be playable in Halo 4’s featured playlist until April 28. Be sure to check out the full details on Monday’s matchmaking updates over on Halo Waypoint.
