What does Magnetic Grenade do?
Magnetic Grenade is bound to Cassidy's Ability 2 which is by default.Magnetic Grenade homes in on enemies close to the reticle. If no target is found, it will travel 10 meters. If it chases a target, it can travel up to 13 meters. It can deal up to 131 damage (1 impact, 65 explosion, 65 directly to target) to the stuck target and 65 damage to non-stuck enemies from its explosion.
How do I unlock Gotcha?
Gotcha requires you to get 2 killing blows (not just assists) so it's a bit tough. While this is easier said than done, you can get a shot onto a 200 health hero, stick the grenade onto them, and get two body shot/one head shot onto another 200 health enemy that will take splash damage.
Alternatively, some ultimates that stun, such as Reinhardt's Earthshatter and Mei's Blizzard, or Zarya's Graviton Surge can make this achievement a bit simpler.
How do I boost this achievement?
The Lockdown Method
This is the most common method to boost Overwatch that requires 10 people.- Get a group of 10 people.
- Get into two groups of 5
- Disable cross play
- Queue for Quick Play Open Queue at the same time and hope it matches you guys up
- Once you match up, get two enemies' health to a little over 65 and under 65 and have them stand together. Stick the grenade on the one over 65 and you should get the final blow on both.
Remember to keep the objective contested unless it's a Control map which will not need contesting unless someone captured it.
