Evolving core gameplay 5 years after release
At some point we introduced Titans to War Robots. Titans were a completely new gameplay element. Now during combat every player became able to summon a massive super-powerful robot in addition to their regular roster, like using an ultimate. Titans required careful core gameplay integration, new balance approach, new meta loops and all of that without breaking the already existing game. My role there was writing concepts for all layers - core gameplay, balance, meta, and monetization. Then coordinate development and integration efforts. Being a mini-lead for a massive feature. What's important about it - it's difficult to introduce such a drastic core gameplay change without breaking a game apart, but we managed.
