Marathon
Map Reads
Marathon maps reward people who know which corridors are highways. If you always take the main road, you will meet everyone with a gun.
Name the highway
Every map has a loud route between POIs. Use it when you want fights. Avoid it when you want an extract.
Elevation and interior loops beat sprinting the objective marker in a straight line.
Compression late raid
As extracts shrink, people funnel. If you are still looting a dead wing, you will get pinched. Move with the collapse, not against it.
Callouts are short
Ping a room. Do not write a paragraph. Your teammates are also shooting.
Players who like short recaps can find more in this field guide.
