The United World Government has almost finished building their Warhead Antimatter Response (W.A.R) facility. Your Heist Crew cannot let that happen. Are you up for the challenge? Grand Theft Antimatter is a groundbreaking printable escape room game that brings all the fun of escape rooms into your own home. The game is designed to be played by teens and families at their own pace, in their own space. Players will take on the role of one of the members of the Heist Crew, and work together to steal the antimatter before the W.A.R facility goes online. Gameplay is centered on a series of puzzle cards that players must solve. Each card solved progresses the story and brings players closer to completing the heist. Game setup is quick and spoiler-free, and hints are handled by an online hint system that players access on their smartphones. This means that no game master is required to supervise the experience, so you can join the game alongside your players. The Warhead Antimatter Response facility is nearly online... do you accept the mission?
