Hollow Knight
Released on February 24, 2017
A 2D metroidvania with an emphasis on close combat and exploration in which the player enters the once-prosperous now-bleak insect kingdom of Hallownest, travels through its various districts, meets friendly inhabitants, fights hostile ones and uncovers the kingdom's history while improving their combat abilities and movement arsenal by fighting bosses and accessing out-of-the-way areas.
At the outset, the player-controlled insectoid warrior arrives in Dirtmouth, a quiet town that sits just above the remains of the kingdom of Hallownest. As the protagonist ventures through the ruins, they learn that Hallownest was once a flourishing kingdom of insects which fell after becoming overrun with "The Infection", a supernatural disease that can infect anyone by entering the subject's dreams and controlling their minds and wills. The Infection gives its subjects heightened strength but at the cost of their civility, causing madness and undeath. Hallownest's ruler, The Pale King, had previously attempted to lock away the Infection in the Temple of the Black Egg. Despite the temple's magical seals, the disease managed to escape, and Hallownest fell into ruin. The protagonist's mission is to find and kill three bugs called the Dreamers, who act as the living seals on the temple door. Once the seals have been removed, the player may confront the source of the Infection. This quest brings the player into conflict with Hornet, a warrior who tests their combat prowess in several battles.
