GDC Europe 2013 organizers have added new lectures for its August event, covering Halo's first episodic multiplayer content, Top Eleven's emerging market efforts that led to 11 million monthly active users, and Bigpoint's C++-to-web tech overview. These talks are part of the programming, design and business tracks in GDC Europe 2013, which will take place Monday through Wednesday, August 19th-21st at the Cologne Congress-Centrum Ost in Cologne, Germany - just ahead of (and co-located with) the massive 275,000 person Gamescom event. In 'The Making of Halo 4's Episodic Co-op Adventure: Spartan Ops,' 343 Industries' lead designer Chris Haluke will share his design details behind Xbox-exclusive franchise Halo's first ever episodic multiplayer content. This talk will outline some of the key pillars Haluke stood by, including maintaining accessibility, creating compelling but bite-sized chunks of gameplay, and ensuring that fiction is continually tied to the adventure. Next, Nordeus' head of business development Nikola Cavic will present a strong example for success in emerging markets, arguing that these markets have lucrative populations and monetization levels but are ignored by developers. In 'Top Eleven: Achieving global success via emerging markets,' Cavic will share how Nordeus targeted and embraced markets outside of the US and UK to achieve over 11 million monthly active users and 40 million registered users within three years for its online sports management game. Last, Battlestar Galactica Online and Drakensang Online publisher Bigpoint's head of development Andre Weissflog says that the technology is here to port large 3D games, but it is not without its pitfalls. In his 'C++ in the Browser: a tale from the trenches' lecture, attendees will learn about the current state, advantages, and disadvantages of 3 C++-to-web technologies. Weissflog will speak about Native Client, flascc and emscripten, with a strong focus on emscripten. His tips will include how to prepare and port their existing code bases and how to deal with the limitations of running in a browser environment. More talks will be revealed throughout the months leading up to GDC Europe in August. Early bird registration for GDC Europe 2013 is now available, with discounts up to 20% off admission.
