The risk was calculated... but man am I bad at math.
This section outlines a strategy. Feel free to add tips, tricks and general advice about the topic.

  • Impulse Grenades are very good for fast mobility, as they can launch you into the air or forwards.
  • Impulse Grenades can be used to launch enemy players into the storm.
  • If a player is fast, they can throw a Impulse Grenade down near an item, quickly swap it out on the very short delay before the grenade detonates, and utilize the grenade whilst keeping the swapped item. This of course uses the grenade up, but it can be useful as to not waste the grenade.
