Killjoy

Killjoy uses gadgets that work for her:

• Turret (signature): a turret you place that shoots enemies entering its field of fire in front of it. It gives information (if it fires, someone is there) and deals damage;
• Alarmbot: a hidden bot that, when an enemy comes close, chases them and explodes, making them vulnerable (they take more damage);
• Nanoswarm: a grenade that, once on the ground, stays hidden; when you activate it, it releases a swarm that deals damage in the area;
• Lockdown (ultimate): a device that, after a long wind-up, detains every enemy in a very wide radius. It can be destroyed before it activates.

Killjoy's gadgets switch off if she goes too far away: she is a sentinel who holds the area she is in, not the whole map.

Pick Killjoy when:

• the team needs someone to hold a site alone: turret, bot and grenades do the work of several players, buying time and information;
• you are learning the sentinel role: the gadgets are simple to use and pay off straight away, even without complicated setups;
• you want a sentinel who is extremely strong in the post-plant: hidden grenades near the spike make defusing very hard;
• the map has big sites that one person cannot watch alone: the gadgets cover the angles she does not see.

Lockdown is one of the strongest ultimates for retakes and executes: a whole site detained for a few seconds opens up any situation.

Killjoy is also a great agent for learning to read a site: placing turret, bot and grenades forces you to think about where the attack will come from, which angles it will check first and where it will stop to plant. It is the same reasoning you need with any sentinel.
