How to complete the Spiker Studies objectives in Rainbow Six Extraction

Spiker Studies is a set of Study objectives in the New York City region of Rainbow Six Extraction. Each of the three objectives involves Spikers, which are humanoid Archaeans that look very similar to Grunts, only their heads and hands are covered in spikes. While Grunts can only use melee attacks, Spikers can shoot spikes out of their hands.

To cover a Spiker with smoke, equip your Operator of choice with Smoke Grenades, then start an incursion and go looking for a Spiker. They’re very common and will typically spawn in Moderate Threat Level incursions, although not necessarily in every Sub-Zone. All you have to do to complete this objective is throw a Smoke Grenade that detonates close enough to a Spiker to cover it with smoke.

It’s generally better to take a Spiker down with a stealth melee attack or headshot before it even knows you’re there, but if you do alert one, then it’ll make an easy target of itself by howling for a few seconds. This is your last chance to shoot it (ideally in its weak point, the head) before it starts opening fire with spikes. Once it starts shooting, you’ve missed your chance to get this objective, so go and find another un-alerted Spiker.

But, if you work as a team, a squadmate can draw
