Grand Theft Auto IV's second downloadable episode, The Ballad of Gay Tony injects Liberty City with an overdose of guns, glitz, and grime.As Luis Lopez, part-time hoodlum and full-time assistant to legendary nightclub impresario Tony Prince (aka "Gay Tony"), players will struggle with the competing loyalties of family and friends, and with the uncertainty about who is real and who is fake in a world in which everyone has a price.Luis may also be called upon to assist a VIP who needs help with a problem, often after doing enough work in Club Management, which can see him bringing a VIP somewhere or doing a task for them.The Underground Fight Tournament can see the player either being a spectator in which they bet on a match's outcome, or enter themselves and take on a variety of different opponents.The new weapons featured in the game include the Advance SMG (can't be used for drive-bys), the Gold SMG, the Advanced MG, the .44 Pistol, the Advanced Sniper Rifle, and Sticky Bombs.The Grenade Launcher and Assault Shotgun from The Lost and Damned also return, with the latter capable of firing regular or explosive rounds.
Club Management focuses on Luis keeping an eye on one of the clubs, where he acts as a bouncer and moves between different areas of the club (such as the Bar or the VIP lounge), dealing with anyone who is highly drunk, causing trouble, or dealing drugs, while on some occasions, he may be called to check in on the club's manager, Joni.
Unlike Johnny, Luis may change his clothing at his safe house, but between various outfits.
Like The Lost and Damned the display and hud are modified from that of Grand Theft Auto, while the map now includes an altimeter whenever the player is in a helicopter or skydiving/parachuting.
If competing themselves, they must complete a round in which they must beat three opponents, one after the other.
The player can either fight with their fists or with melee weapons they can acquire by disarming opponents who bring them in, and can gain assistance from the audience to take down an opponent by pushing them back into the arena's cage wall.
