Frosting on the Cake

Frosting on the Cake is a mission in The Ballad of Gay Tony. It is given by Gay Tony to Luis Lopez.

Mission

The mission starts showing Gracie, Sharon, Evan and Rocco having a coke hit at Tony's apartment. Luis walks in looking for Tony, who called him in earlier. After having an exchange with Rocco, Luis finds Tony passed out on the floor. After waking him up with a brisk dunk in the bathroom sink, Tony tells Luis that they're going to purchase some 2 million dollars worth of diamonds off a smuggler in Broker. As they leave, Evan decides he wants to go as well.

Mission objectives

In order to complete the mission the player must:

Go to the docks
Use sticky bombs to take out the bikers
Lose the cops
Drive Tony back to the club

Walkthrough

Drive the Stretch E with Evan to the docks where the Platypus in Broker, where The Cook is waiting. Listen to Evan whine, but try not to damage the limo too much. Once you arrive, a cutscene will start showing the deal going down. At first everything is fine, but soon Johnny Klebitz and the Broker Chapter of the Lost biker gang show up to crash the deal. Luis and Tony will dive into one limo, and Evan with the diamonds jump into another. Now, instead of driving, you'll be riding shotgun, with the camera facing behind the car, and are given Sticky Bombs in order to hold off of the chasing bikers and trucks. Try to aim for their front tires, and destroy roadblock as soon as you get to them. Once you near the Algonquin Bridge an APC will show up, along with a NOOSE Annihilator. Throw as many Sticky Bombs as you can until the APC explodes, and 2 or 3 to drop the chopper. At the end of the bridge, your driver is shot and you must lose the heat, regaining control of the limo. Lose the heat, and go to Hercules to end the mission. The mission ends when Tony tells you that Evan was killed, apparently while bleeting online about his impending doom at the hands of Johnny Klebitz, and the diamonds are lost.

Deaths

Costas - Killed by the LCPD while trying to escape from the bikers.
Evan Moss - Killed by Johnny to steal the diamonds. (His death is not shown in this mission)

Trivia

This is the only mission that NOOSE actually utilizes the APC.
If the Stretch E is destroyed or Evan is killed before the deal, the mission will fail.
In TLAD, Johnny only had a few bikers with him but in this, he is accompanied by a small army of bikers.
When the Stretch E is driving of from where the deal was busted, you can see several Lost members and bodyguards fighting.
This mission, along with Diamonds in the Rough are the only crossover missions in the GTA IV era to not involve Niko Bellic.
This is the only mission which the Slamvan appears in TBOGT.
This mission is simiar to the GTA SA mission Reuniting The Families, in a way that both missions require the player to fend off pursuers from a car using a weapon, including motorcylists and a helicopter. Some differences are that CJ used an AK-47, and had to keep the car from being destroyed, with only police as enemies, while Luis uses sticky bombs, and fends off both police and Lost MC bikers.
in the cutscene where Costas is killed, a police officer is seen shooting at the limo, but sometimes he will not fire, although Costas is still killed.
