The Gates of El Presidio

Teleport or ride to the 'R' on the map to start the mission.

After the opening cutscene (a non-interactive cinematic the game plays automatically) (a non-interactive cinematic the game plays automatically), ride shotgun with Reyes in his wagon, which is backed to the hilt with explosives.

Abraham Reyes will persuade you to drive the explosives-filled wagon right up to the front gates of the fort.

Warning: Press Y/Triangle to jump off the wagon when prompted on the screen. If you jump too early or too late, you’ll auto-fail the mission.

Once the gate is blown open, scarper to cover (press the cover button to crouch behind walls or objects) (press the cover button to crouch behind walls or objects) and let the revolution men through first.

Equip your best rifle and get inside behind some cover. Three question marks will appear on the map; two indicate towers, whilst the third (the barracks) doesn’t, and this is where Escuella is always found hiding.

After a cutscene, Escuella will make a run for it into the desert on his horse! Call your horse when you get back outside the gates and chase after him.

You now need to decide whether you wish to gun the traitor down, or lasso him and take him alive.

Whatever choice you decide, you ultimately need to take his body back on your horse and dump it in the cells in the fort.

Reinforcements are on their way, so jump up onto the tower covering the front gates and man the huge back cannon.

The cannon balls have a huge explosive arc, so they’ll easily take out the groups of horses and wagons that attempt to pull up to the fort (especially if you fire the balls into the middle of any groups).

Put Escuella back onto your horse and take him to the two FBI agents that are located on your map (by the bridge that connects with America).
