The tests used in standards for evaluating smoke alarms were developed back in the 1980s. However, despite changes in building materials since then, smoke alarms remain reliable, says Chagger: "They still respond to all the main fires we get today."
Towerborne was originally envisioned as an always-online MMO-lite action RPG brawler. Players would group together with their friends in a shared social space known as The Belfry. From there, players would venture out to the hexagonal world map and enter into 2.5D side-scrolling brawler combat missions. Loot, quests, and an ever-expanding world map provide a compelling "just one more" gameplay loop. The live-service structure meant the game would be ever-changing and expanding with new content and features continuously releasing over time.
