Warena features a fantastical action-survival gameplay, released in two phases. Its first phase is a 2D tower defense game set in the year 2129, in the so-called Survival Phase. After the Earth has descended into World War 3 and witnessed the widespread use of biological and nuclear weapons, it has turned into a post-apocalyptic scenery, with the remaining humans fighting zombies for survival. Players have to cooperate with robots to collect glass spheres, the in-game currency, to level up the robots’ engines, and optimize machine parts. The second phase will take place after a Big Bang that fragments the universe into different dimensions and creates the game’s metaverse, where different tribes like fairies, demons, and humans are present.
