Driller

Driller is a heist setup mission in Grand Theft Auto V required to do the obvious approach in The Big Score heist.

Overview
Lester will send a text message to all the protagonists, saying that the Cutter has arrived in a warehouse in East Los Santos, and that the place is full of guards. He recommends stealing the Cutter without alerting the guards.

Mission
To steal the cutter without being noticed by the guards, it is recommended to use stealth mode to knock out all the guards before entering the Cutter. If the player enters the vehicle and at least one guard is still alive, the player will be automatically detected. Weapons equipped with suppressors are also helpful, especially snipers. It is important to note that being detected does not fail the mission, it merely fails one of the gold medal objectives.

Once all of the guards are neutralized, enter the Cutter and drive it out of the yard; the protagonist will call Lester and he will direct the player to deliver the drill to a parking lot near the Union Depository. Once the Cutter is delivered the mission is complete.
