Uncharted 4 - How to beat Chapter 20 on Crushing Mode

1. In the beginning shoot empty your primary weapon (so its faster to grab a new one later) 2. Hide behind the cliff and kill all people who can reach the platform right beyond you 3. Kill all on the higher platform (opposite site) 4. Quickly kill the 2 people left on the boat (in the middle) with 1 grenade, since the last kill (on number 3) triggers new enemies 5. get onto the higher platform and kill all enemies who r running towards u before they can enter the area 6. Throw grenades to the slower ones and grab a sniper 7. Go back to the beginning platform and kill all left opponents with the sniper (be patient)
