In a new blog post, Infinity Ward has posted a lengthy post about the new tactical equipment the 9-bang.

The 9-Bang uses a tiered power system to determine its impact. The longer your character holds the equipment before throwing, the more blinding flashes it produces on detonation. A fully cooked 9-Bang additionally releases an EMP effect that stuns nearby electronics, temporarily shutting down enemy defenses.

“The 9-Bang’s power system challenges players to plan ahead and think more tactically when engaging enemies,” says Multiplayer Lead Tom Wells. “Caught unaware? You can still toss it right out like a traditional flash grenade in a hurry. Prep a fully charged 9-Bang, however, and you’ll disrupt defenses in a big way.”

It’s important to consider how much power you need in each situation compared to how much time you have for priming. The longer the charge, the more effective the blast.

If you’re assaulting an objective point, the fully primed EMP effect really comes in handy. In addition to blinding defenders in the vicinity, you’ll temporarily shut down nearby Sentry Guns, I.M.S. devices, and a variety of other electronic dangers. With planning and preparation, you can greatly improve the likelihood of capturing the objective.

Of course, there are several counters to consider when using the 9-Bang:

Tac Resist

Resistance to flash, stun and EMP effects.

The Tac Resist perk greatly increases resistance to the 9-Bang’s effects. This obviously benefits enemy targets, but it’s also worth considering if you plan on equipping the 9-Bang yourself.

Equipping Tac Mask reduces the penalty of deploying the 9-Bang in close proximity, allowing you to play more aggressively without as much worry about potential backfire.

Trophy System

Active defense turret that destroys two enemy projectiles.

The Trophy System Tactical equipment counters up to two projectiles, including the 9-Bang, fully charged or not. Be prepared to defend yourself if your equipment gets vaporized.

Night Owl

A companion drone that detects enemies based on proximity and protects you from explosives.

Found in the Support Strike Package, the Night Owl protects its user against multiple explosives, including the 9-Bang. At a cost of 10 points, they’re not something you’ll run into left and right, but they’re a real pain when encountered. Use a non-explosive weapon to take them out on sight.

With practice, you’ll start to get a better feel for power vs. timing. Plan ahead for maximum impact and reap the rewards of more points and match victories.
