Hitman: Absolution

Normally this game has its own pages for speedruns, but I put this one together to note down the icons used for Maximum Ratings run:

Silent Assassin
Can be achieved only in levels with the targets. Requires killing the target, while not getting spotted.

Shadow
Achieved in checkpoints that have evidence and targets. You need to collect the evidence and not kill anyone in the checkpoint. If you knock out someone, a budy must be hidden.

Specialist
Don't get spotted and don't kill anyone. There also isn't a need to hide unconscious bodies. There exists only 2 checkpoints like this - Burning Hotel and Dressing Room.

Veteran
No image, sorry. This one is glitched, as normally you should be able to achieve Shadow rating in Gun-Shop level, but someone apparently failed at QA, so the highest rating on that level is Veteran, despite the fact you need to pick up evidence.
