How do I use smoke pellets in the Search and Destroy campaign?

Question

To earn the Smoke Detector medal in the Search and Destroy campaign, I have to

Use the Smoke Pellet to create a smoke cloud and take down a henchman as he panics in the smoke.

I've hit ← twice on the D-pad to select the smoke pellet, but pressing L1 throws the batarang. Holding down L1 doesn't seem to work either. How do I use the smoke pellet? Is it a future gadget upgrade?

Answer 1

You can toss a smoke pellet in the following ways:

• Tapping triangle while under fire
• Choosing it, aiming with L1 and tossing with R1
• Tapping R2 while aiming with L1

You can always review the controls by going into the WayneTech menu and choosing Smoke Pellet under Gadgets
