The bosses are back. Last month you beat the Feds. Now it’s time to take on four crime lords from San Juan. This ten-day fight fest starts today, and it’ll take the power and dedication of you and your strongest mafia members to defeat these Puerto Rican bosses.

Each time you take out a boss – there’s Señor Carazco, General Vargas, Don Ramirez and Big Lou – you are rewarded with Vegas chips, experience points, victory coins and powerful loot. The more bosses you beat, the more powerful your items and bigger your bonuses become.

San Juan bosses give up some sweet loot when you beat them. These include: a Set of Throwing Knives weapon (highest value tops at 49 attack/87 defense), an MG Gloss 350 vehicle (57 attack/95 defense), a Night Vision Viewer armor (106 attack, 71 defense) and a Red Piranha animal (110 attack, 82 defense).

Your boss fights in San Juan won’t be easy. First, you have to finish off bosses in a specific amount of time. Once time runs out, a boss recovers to full strength, which means you’ll have to start over if you don’t win the fight. Bosses also get tougher after every time, so it’s critical that you get your mafia to help you. Friends who help beat a boss share rewards with you. Don’t forget to help your mafia too. Top helpers also collect the bosses’ loot for helping their mafia win.

There are three mastery levels – bronze, silver and gold. You must defeat all four bosses to receive the mastery item, an Outlander vehicle. The Outlander increases in value each time you master a new level and tops out at attack 112/defense 58.

Help your mafia fight the good fight to collect items, and make sure they are there to go to battle with you in San Juan.

First and foremost, players expect and deserve a reliable game performance. We are always open to your feedback, and the top priority for us is to fix the bugs in our game. This is why we’ve dedicated this week to have our entire team work on these issues.

On Thursday, we cleaned up a lot of bugs to improve the quality of the game. Some of these issues include cracking down on cheaters who exploited a loophole to level up infinitely in Las Vegas. We have zero tolerance for users who abuse the system to give themselves an unfair advantage. We also fixed an issue that didn’t allow some users to send or accept free gifts. Now you can send building materials to friends to upgrade casino properties and chop shops and help them finish their Challenge Mission in Mumbai.

Developers are also fixing issues with It’s On in San Juan, a new limited-time boss fight. We released It’s On In San Juan on Thursday evening. The overwhelming popularity of the event forced us to make adjustments to improve the game performance. We’ve made this our priority to ensure that the feature is reliable and ready for a full release. We will be extending the boss fight event to make sure everyone gets a chance to take down the San Juan bosses.
