Legion 51 is dedicated to a real-life event called “Storm Area 51. They Can't Stop Us All.” One of the users suggested on the Internet that other users gather in the Nevada desert and make their way to the US Air Force base, where, according to fans of conspiracy theories, experiments were carried out on aliens. The idea went viral, and in September 2019, many people actually gathered at a military facility. However, no one began to storm anything then. Everything was limited to holding the festival. In the wake of the hype, an indie developer released a comic game in which he fantasized about an alternative development of events. This small project can be completed in one evening.

Legion 51 is a representative of the tower defense genre. Only here gamers are offered to play the role of attackers rather than defenders. Here players command a raid of Internet users who are trying to break into the base. And the American military is firing at them to kill. There are different units with their own abilities. Some of them can be exchanged for heroes who have unique skills, such as healing allies. They can also give units various bonuses. To place people on the field, you need to spend hype points. To attract fans and increase crowd sizes, you need to stream, take selfies and record videos. The point of the gameplay is to correctly place your players to increase the chances of reaching their destination.
