Cleaner is an achievement/trophy in Dishonored.
How to Acquire[]
To unlock it, Corvo Attano must fight five enemies at once and make sure none of them survive. A simple method of acquiring this achievement/trophy is get attract the attention of a large group of enemies - five, or more to be on the safe side - and use Blink to evade them or hide normally. Before they disperse, Corvo has a few options to get the accolade, including (but not limited to):
- Throwing either a grenade or a sticky grenade into the group of enemies. If timed right, they will not notice in enough time to escape, and the group should be killed.
- Placing a spring razor on a specific spot on the ground, prior to attracting the attention of the enemies and baiting them to the spring razor. However, this technique is usually ineffective, as only the first few are killed, and the rest are injured.
- Shooting an incendiary bolt into a group of enemies, setting most, if not all, alight. This will eventually kill them, but is less effective than the grenade method.
