One of those launch events took place alongside the River Thames, where the platform holder arranged for a giant glyph to be suspended from a helicopter, providing dramatic scenes (and puzzled looks if you didn't know what the symbol represented) alongside Tower Bridge.
Ahead of the stunt CVG sat down with exec producer Kiki Wolfkill, who kindly reflected on the pressures of assembling a team and living up to the standards of one of gaming's most celebrated series.
After years assembling a team and dealing with the pressure that comes with creating a Halo game, how does it feel to finally see Halo 4 released?
You know it's funny because there's been so much going on between from when we got the game done and now with press, events and reviews coming out... I think it really hit me on the drive over here to the launch event. This isn't just another event that I'm coming to - this is the launch. It's crazy because this is the moment when the fans get it. As much as it's fantastic to hear from reviewers, to hear from the fans is a pretty emotional moment.
So yeah, it's a sense of relief and a little bit of nervousness.
But the critical reception has generally been very good. Does that justify the hard work and late nights for you personally?
It does because I knew this team was going to be capable of doing something amazing. It all came down to how much time we had and how much we could pull everything together. I feel such pride in what we've created together. For me the other part of that validation is the community sort of feeling the same thing.
Often you don't get enough credit for the amount of pressure you've been under to live up to Bungie's Halo games - and going by the review scores you've more than matched them. In hindsight do you think the pressure might have helped in some way?
Yeah. Everyone stepped in to this knowing how big a challenge it was going to be. We knew the pressure was going to be there and ultimately we put the most pressure on ourselves to deliver something that we believed in and the fans could believe in. It absolutely empowered us.
I think there was a sense for us as kind of being the underdog as well, which I think was part of the emotional motivation behind the team, because everyone who came to 343 had a certain level of success - and in some cases a lot of success. So this was an achievement that was really meaningful.
What can the 343 team take out of the Halo 4 development process in terms of what you think you did well and what you can improve going forward?
Gosh, you learn so much along the way. It was definitely a rocky ride and part of that was the challenge of putting a new team together, learning to work together and sort of navigating that. I feel good about keeping pressure off of the team in terms of all the other things that happen when you're a really important IP.
It takes time for a team to build trust with eachother and we were absolutely able to do it through the cycle. If I look back, I had an amazing leadership team. I think there were times when I perhaps kept things close to me because... you want so much for everything to go right. As a leader one of the critical things I learnt during this process was learning to let go enough for my leadership team to really excel. Thankfully I figured that out! (laughs)
