Critical reception for Xeno Crisis has varied depending on the version; the Mega Drive/Genesis release garnered generally favorable reviews, while the Switch port received average reviews.

Criticism was geared towards its difficulty, short length, and issues when playing with the Mega Drive's three-button controller.

## Gameplay

Xeno Crisis is a multidirectional shooter game similar to Robotron: 2084 and Smash TV. The premise begins with Commander Darius receiving a distress signal from Outpost 88, a scientific research facility overrun by aliens. The space marines John Marsh and Sarah Ridley are dispatched on a drop ship to confront the aliens at the facility. One or two players control either Marsh or Ridley, and work their way through seven procedurally generated levels. There are a number of enemies of various difficulty in each room, concluding with a boss battle at the end of most levels. After enemies onscreen are killed, a chance of an item, a weapon drop, health, or dogtags are dropped to aid the player. Dogtags are used as in-game currency to buy upgrades such as additional health or increase the player character's speed. The starting machine gun has limited ammunition, and weapon pickups have a time limit, requiring players to stay on the move and on the lookout for ammunition boxes. Along the way, players will come across with survivors of the facility that can be rescued and released to safety.
The game employs a twin-stick control scheme, which allows for an eight-way input direction; the d-pad or left joystick controls the on-screen character's movement, while the buttons or right joystick controls the direction the character's weapon fires. The player character is equipped with a limited supply of grenades, capable of obliterating any enemy caught within its blast radius. If a player character runs out of bullets and grenades, they can perform a close-range melee attack against enemies. The player character can also perform an evasive roll maneuver to dodge enemies and enemy fire. There are over ten weapon pickups, each with their own characteristics, ranging from flamethrowers, homing shots, lasers, rocket launchers, and shotguns. The characters can withstand a limited number of enemy hits but the game is over once their health are depleted, though players have the option to continue playing using elixirs that can also be purchased. The player can access the game's options screen to change configurations such as controls, difficulty, among other settings.

The campaign ended on January 10, 2018, raising £72,569 ($92,271) in total. It was first slated for October 2018, coinciding with the 30th anniversary of the Mega Drive's Japanese launch, but Bitmap Bureau later announced that the game would not be ready by 2018, due to production slowing down.

Xeno Crisis on Nintendo Switch garnered "mixed or average" reviews, according to review aggregator site Metacritic. Nintendo Life's Jason Brown reviewed the Switch port, praising the game's design, fast-paced gameplay, and cooperative mode, but criticized its difficulty for being off-putting for inexperienced players. Vandal's Ramón Nafria praised the game's graphical presentation, audio, and two-player mode, but noted that it can be difficult for one player. 4Players' Matthias Schmid highlighted the game's visuals, controls, soundscape, challenge, and rudimentary character leveling system. Nevertheless, Schmid saw aspects such as the "down-to-earth" playability, scope, and bosses as shortcomings. Sega-16's Ken Horowitz gave the Sega Mega Drive/Genesis version positive remarks for its engrossing arcade-style gameplay, artwork by Henk Nieborg, and soundtrack by Daniel Bärlin (Savaged Regime), but noted its difficulty and faulted its short length.
M! Games' Thomas Nickel reviewed the Switch port, commending the game's frenetic action, large bosses, difficulty, controls, multiplayer, and pixel art. Retro Gamer's Darran Jones regarded it as one of the best arena shooters on the Mega Drive, highlighting its "ridiculous" action, co-op play, and bosses, but noted its difficulty and issues when playing with the Mega Drive's three-button controller. Jones also called the Nintendo 64 version "superb", comparing it favorably with the Dreamcast version, but felt that an option for customizable controls would have been a nice addition. Reviewing the Mega Drive version, Wireframe's Ryan Lambie praised the game's polish and gameplay, but criticized some design decisions like the weapon upgrades and the melee attack feature. Hardcore Gamer's Marcus Estrada analyzed the Mega Drive version as part of the Xeno Crisis & Tanglewood compilation for Evercade, stating that the difficulty and random-generated stages made it a replayable title.
