[Editor's Note: This page has been updated with the Rewind Theater above that breaks down the trailer frame-by-frame, revealing some fascinating new details about the Heists you'll be doing in the game. See the regular trailer below.]

To say we've waited a long time for multiplayer Heists to get added (for free, by the way) into Grand Theft Auto Online would be the understatement of the year. The bad news is that we still don't have a concrete date for when it's finally happening. The good news, however, is that we do now have a killer trailer showing them off as well as an interview with GTA Online producer and lead mission designer Imran Sarwar, who was kind enough to answer our (many) questions about this high-concept feature.

"Funny, he told me the same thing..."

Looks like we're breaking a buddy out of the slammer before he even gets there.

“ After many months of designing, testing, rewriting and re-testing, we settled on the four-player structure that you will experience in the game. It took a ton of work from our programmers and mission designers to make it work at the level we were happy with.

"Doot doo doo, don't mind us. Just collecting the garbage..."

“ Heists will be ready early in 2015.

"Let's hurry up, Bill. The sweat is making my paper bag stick to my head."

“ Switching between the roles of crew member and heist leader will give players a totally different experience...

"Hey, are we locked in here?"

"Could we, uh, get away faster in our getaway car?"

“ Some missions have all players working as one unit, some require players to take on specific tasks like hacking or crowd control, while others require players to split into smaller teams to complete separate high value objectives.

"Dude, did you wash these masks after last time?"

“ There are five unique strands involving over 20 total missions, which will add up to around 20 hours of gameplay.

They don't even have to change outfits in order to make meth when they get home!

"Do you have any idea who you're stealing from?"

We rob hard, we play hard.

Slipping away from the authorities.

Another look at that breaking-your-buddy-out-of-jail-before-he-gets-there.

Speeding violations get taken REALLY seriously by the police these days.

Sun's out gun's out.

And you thought the Army of Two franchise was dead...

Lester will help you get your Heists set up.

Ah yes, the cool-person walk away from the camera after the heist is over.

Hmm, what are they shooting at here?

IMRAN: To be honest, they just turned out to be a lot more difficult than we originally thought.Our initial idea was to build on the concept of Story Mode heists to make a new gameplay experience for GTA Online that was more focused on cooperation, where everyone could play to their individual strengths and feel like they had a stake in the outcome.As it turns out, creating missions of that complexity for multiple players at the same time was much more difficult than we anticipated and every time we thought we were close, something would send us back to square one. Having already let players know of our intentions with Heists, every setback only increased the pressure to make sure we got them right.One of the challenges is that unlike a heist in Story Mode, every player needs to feel central to the action at all times, and that’s much more challenging than it appears.A good example is the classic idea of your getaway driver, waiting outside of a bank for the big score. A movie might not spend too much time focusing on that person because while they are waiting, we are watching the action going down in the vault. In a similar situation in Story Mode, we could use a character switch to make sure the player was always in the center of the action and switch back to the driver later. But to make this work for multiple players, we needed to create situations where the driver has something interesting to do at exactly the same time the rest of their team are locking down the bank and making their way to the money.After many months of designing, testing, rewriting and re-testing, we settled on the four-player structure that you will experience in the game. It took a ton of work from our programmers and mission designers to make it work at the level we were happy with.We never want to have to move a date but if something is delayed, it’s because it’s not at the level we expect of ourselves. And while we’re not there yet, we’re getting close and Heists will be ready early in 2015.IMRAN: Each heist requires 4 players all at rank 12 or above, with one player as the designated heist leader. Leading a heist requires owning a high-end apartment so that you have a room available to set up the planning board. From there you’ll be able to launch missions as the leader, starting with the prep work and building up to the score itself.Being a heist leader has advantages and disadvantages. On the upside, Lester contacts the leader directly when there’s news of a job and it’s up to the leader to invite players into the crew, assign positions, pick outfits and allocate each player’s cut. On the other hand, the heist leader will need to personally front the set-up costs in order to successfully pull off the heist.Some missions have all players working as one unit, some require players to take on specific tasks like hacking or crowd control, while others require players to split into smaller teams to complete separate high value objectives. For example, one team may be stealing a getaway car from some gangsters while another team is attempting to sneak into a police station, all within the same prep mission. We really want to push the co-op aspect and make players feel like they need to communicate effectively and work together to pull off each element.Each finale is a big set-piece mission with players taking on multiple roles. All through this, players will be gaining access to new vehicles, new weapons, new items and new clothing, as well as visiting some surprising locations and interacting with some familiar characters from the story.IMRAN: Definitely. And they had to. It took several passes from scratch before we settled on the design we have now. Prep and set-up missions in Story Mode could be relatively low-key affairs, but with four players and an emphasis on replayability we felt like we needed to make these as diverse and as fun as possible. This required a totally new way of testing as we formed into teams and played and replayed a huge range of scenarios in order to make sure the balance and timing of each section felt right.We also added trip-skips to allow players to skip longer drives if they have already played the mission as well as carefully balancing checkpoints, with a range of difficulty levels to give players of all skill levels a real challenge. We have also tried to add player choice wherever possible, from the clothing to the tactics involved and so on.We have several rewards for players as well, such as for playing all five heists in order with the same set of players and another bonus for playing all of them in first-person [mode] on PS4, Xbox One, or PC, as well as Elite Bonus Challenges, which are essentially a big cash reward if you complete each part of a heist while meeting certain criteria, such as time to complete, damage taken, accuracy etc.IMRAN: I don’t want to spoil a whole heist, but a favourite would be the finale of an epic prison break where players come from different points on the map to join together at just the right time. It requires a pilot, a demolitions expert, and some undercover work to pull it off, and it takes real teamwork, the ability to think fast and a lot of communication to put all the pieces in place to extract the target flawlessly. It’s also a heist that isn’t just about stealing money, and it is definitely not about going in all guns blazing.IMRAN: Right now we just want to get Heists out there and get real world feedback before we look too far ahead. Reaching this point has obviously taken much longer than we ever thought it would and we know we have a lot to live up to, but we’re looking forward to finally being able to share them with other players soon.
