Risk of Rain 2

Risk of Rain 2 is a cooperative third person shooter with roguelike elements. Players control a stranded survivor that must escape from a hostile alien planet. In the beginning of the game, players can choose between several survivors, each with a unique set of abilities which require different approaches to gameplay. Players must then progress through a series of levels; on each level, the goal is to kill alien enemies while locating a teleporter. Enemies defeated in combat award experience and currency. If enough experience is gained, the player will level up, increasing their damage dealt and maximum health. Currency can be used to open chests found throughout the level, which drop random items; they can also be used to activate turrets and drones which assist the player. Items collected from chests offer a wide range of buffs to the players carrying them and there are no limits to how many copies of an item one character can have, allowing their effects to stack.

Once the teleporter on a level is located and activated, the players must defend themselves from a larger onslaught of aliens until the teleporter is fully charged, upon which the players advance to the next level. Currency cannot be carried between levels, as all currency is converted to experience before teleporting to the next level. As players progress, enemies will gradually level up, increasing their maximum health and damage; this happens passively over time and when players advance to another level. The difficulty of the game is dependent on the current duration, the number of levels completed, the number of players in the game, and the difficulty level—selected at the beginning of the game—which scales the rate at which enemies level up.

There are several possible ways to end the game. When a survivor dies, the game ends; in a multiplayer session, it does not end until all survivors have died. A handful of final boss fights exist; successfully defeating one of these bosses ends the game. There are secret levels—accessible upon meeting certain conditions—that allow players to end a game voluntarily without confronting a final boss. Players can also loop through the levels of the game indefinitely, allowing continued gameplay for as long as players can survive. Regardless of method, when the game ends, all currency, experience, and items are lost.

In the metagame, players can unlock access to new playable survivors, items, abilities, and game modifiers by completing certain in-game challenges; once unlocked, new survivors and modifiers become available to select from at the start of the game, and new items will start appearing randomly from in-game chests. Additionally, there is another currency that has a chance to drop from defeated aliens called Lunar Coins, which persists between games. These coins can be spent at a special vendor in the game, who sells special items and allows players to pick the next level.

Risk of Rain 2 follows a similar approach to the first title, featuring several of the same playable characters, creatures, and items from the first game, but also adds new survivors and most notably transitions the game from 2D to a 3D environment.

When starting development on the sequel, Hopoo began with a 2D-based prototype with the player in control of one of the monsters in the first game, as to mix up the formula for the sequel. The transition to 3D was partly inspired by fan art for the original game that showed the various objects the player collected shown on the character. Hopoo wanted to use this approach for the sequel, but the 2D graphic approach did not give them enough visual space to work with. They transitioned the prototype from 2D to 2.5D, representing the character in 3D graphics but otherwise playing as a 2D platformer, but this did not work to their satisfaction and felt it was better to move the game fully to 3D, with the transition being relatively quick to complete. Hopoo Games noted that the 3D option provided "much deeper design spaces and more possibilities for cool gameplay" as well as more ways to artistically express themselves. The sequel was first announced in May 2017, at which time the team had already been working on the game for 6 months. The sequel uses the Unity engine, which Hopoo had to learn to use, and 3D levels which the team spent a long time making. In designing some of the returning monsters Hopoo noted that they had to design new attacks to make them more challenging in a 3D space. Items also had to be redesigned to deal with the dimension change.

Hopoo released the game into early access on Windows on March 27, 2019; at that time they estimated that the full development process would take another year. During the early access period, Hopoo signed with Gearbox Publishing to release the game on Nintendo Switch, PlayStation 4, and Xbox One. An early access release was announced at Pax West for those platforms on August 30 the same year. Its full release was initially scheduled for Q2 2020 but was delayed in order to expand the scope of its 1.0 update. A free content update titled the "Anniversary Update" was released on March 25, 2021. A paid expansion for the game called "Survivors of the Void" was released on March 1, 2022 for Windows, and the console versions of the expansion released on November 8, 2023, coinciding with both the tenth anniversary of Risk of Rain and the release of Risk of Rain Returns. A second paid content update for Risk of Rain 2 was announced, called "Seekers of the Storm".

In November 2022, Gearbox Entertainment acquired the Risk of Rain IP. Hopoo Games remains an independent studio. Hopoo now states that they are working on other games and projects.

The game was released out of early access for Microsoft Windows on August 11, 2020 and for Stadia on September 29 with a timed exclusive level known as Sundered Grove, which would later be added to all versions in patch 1.0.2.0. The Nintendo Switch, PlayStation 4, and Xbox One received the 1.0 update on October 20 the same year.

On its launch into early access, Hopoo Games offered Risk of Rain 2 with a "buy one, get one free" promotion for the first few days. A week from release, Hopoo announced that over 650,000 players had played the game, with about 150,000 of those having taken advantage of the special promotion. Within a month of the game's early access release, it had sold over a million copies. By March 2021, the game had sold over four million units on the personal computer side alone, not accounting for console sales.
