- "Get a good vantage point then I'll head in when you fire the first shot."
8-Ball, knowing about the meeting after a phone call from Salvatore Leone, tells Claude that he needs $100,000 for the explosives and tells Claude to return when he has the money. After obtaining the necessary money, Claude returns to 8-Ball's and the two head to Portland Harbor, with 8-Ball giving Claude a Sniper Rifle, since his hands are still in a condition bad enough to handle a weapon. After arriving at Portland Harbor, Claude gets a good vantage point (likely the staircase on the warehouse) and begins to kill the Colombian Cartel gang members guarding the Les Cargo container ship, with 8-Ball planting the explosives. He detonates the explosives, getting off the ship's bridge just before it sinks.
In order to complete the mission the player must:
- Take 8-Ball to Portland Harbor
- Get to the vantage point
- Take out the Cartel gang members and protect 8-Ball
- The container ship used by the Colombian Cartel also appears in Grand Theft Auto: Vice City, docked in Viceport.
- If the player is on the ship when it explodes then the player will not die, instead, he will reappear back on land, but the Cartel Cruisers are gone.
- The name of the mission is reused for the "Bomb Da Base II" multiplayer mode in Grand Theft Auto IV, where players are similarly tasked to collect explosives and place them within a ship (Platypus) to destroy it.
- The player will still get the cutscene that shows 8-Ball telling Claude that he needs $100,000 even if they already have the money.
- Despite the fact that Claude is given a sniper rifle, the player can use a rocket launcher as well as getting on board and face the Colombians directly.
- If the player drives a car up the ramp before 8-Ball sinks the ship, the car can be seen hovering in the air after the ship is destroyed.
- A ship very similar to the one destroyed in this mission can be seen in GTA IV, as a deteriorated wreck located off the west coast of Acter Industrial Park.
- There are two missions in Grand Theft Auto III with the name Bomb Da Base Act II, the first one being just a cutscene that involves 8-Ball telling Claude to get the money, and the second one being the real mission.
