Riftfall

Riftfall is a single-player campaign across 20 levels and six biomes, from EMBER GATE to RIFTFALL PRIME. You sprint, double-jump and fight through six sectors in each level, find the RED, BLUE and YELLOW SKULL KEYS to open gates, defeat the level’s boss and reach the Rift Gate to extract. Layouts use seeded procedural generation, so replays differ, and hidden DROP CREDITS reward exploring behind crates.

Campaign and arenas

The campaign moves through burning citadels, frozen vaults, neon war zones, dead wastelands, jungle hells and dune seas, with side trips to a haunted manor, a Mars colony, a storm-wrecked lighthouse and a wild-west canyon. Levels include landmark set-pieces such as a rocket launch silo, crystal cavern, UFO discovery lab, giant pyramid, arcing server room and alien core. Moving platforms, lava crossings and elevators test your double jump; destructible scenery includes cryo capsules, snowman statues, cactuses, windmills and market stalls.

Each level ends at a unique, handcrafted boss arena with a cinematic fly-in, its own rules and a boss that requires more than simply shooting it. These encounters often involve solving a fight-specific challenge:

• The Frostmaw: destroy five glowing crystal towers that heal the ice giant, then bury him in his own castle.
• Magmor the Molten: break the six chains holding an immortal lava colossus above a molten lake, dropping his platform into the fire while you stay somewhere safer.
• The Megabrain: hack four terminals in order to get through the cyber brain’s firewall while its drones hunt you. It is the game’s only boss that talks.
• The Mirror Wraith: destroy the crystals above eight ancient mirrors in a haunted manor to crack the ghost’s reflection.
• The Harbinger: wait for the timed opening in the head crystal’s shield, then attack the 15-meter alien colossus on Mars.
• The Storm Kraken: climb a lighthouse in a raging storm, override its lamp and use the light itself to grip and burn the Kraken.
• The Castle Dragon: use catapults on the castle wall against a dragon impervious to bullets, while knights, archers, skeletons and fire-bats fight in the valley below.
• The Headless Rider: battle across the roof of a moving steam train, wagon by wagon, then face something larger in a ground duel.
• The Neon Colossus: climb the walking titan, break its seals, overload its core and escape through the rift as it collapses.
• Captain Cogburn: fight a jet-boosted pirate captain in a bay, facing his cutlass fan and deployable flame cannons.
• Dune Maw: face a cathedral-sized sand worm that surfaces to eat you, creating an opening to attack.

Other arenas include a pyramid, shark abyss, colosseum, skyhold, neon district and cavern, as well as an endgame arena at the bottom of the campaign. Your squad radios hints, some helpful and some less so. Every level also ends in a boss fight at the Rift Gate. Named milestones include the Iron Revenant in the ruins of DEAD CITY, Oculus Prime in the GREEN INFERNO jungle, Sky Piercer and Neon Harvester stalking the wasteland and neon skyline, and Frost Strider and City Reaper in the ice and city. The final boss is the RIFTFALL DEVOURER. Late-game bosses can change phases; for example, the Rift Tyrant reaches 48% health, announces “RIFT PHASE” and attacks faster and more aggressively.

Weapons and combat

You have six heavy weapons, each with an alternate fire, along with quick melee and a combat dash with invulnerability frames. The Arc Rail has infinite charge, and its Singularity Lance can skewer four enemies in a line before detonating a singularity that chain-arcs to seven more. The Flamethrower can overheat if used too aggressively. The weapons and alternate fires are:

• Breacher: a 12-pellet pump shotgun; Inferno Ram fires superheated beams and shockwaves that break up groups and hurl them backward.
• Vulcan: a spinning-barrel minigun; Arc Grenade bounces an explosive around corners.
• Rift Rocket: deals splash damage; Vortex Salvo fires a full multi-rocket barrage.
• Arc Rail: a piercing railgun with infinite charge; Singularity Lance can skewer four enemies and chain-arc to seven more.
• Rift Sniper: a scoped anti-materiel rifle with wheel-zoom optics.
• Flamethrower: an overheating wall of fire; Napalm Bomb lobs a fuel canister that turns the floor into a burning kill zone.
• Energy sword and grapple: a close-range attack paired with a grapple.

Enemies patrol before spotting you, and can dodge, dig, deploy equipment and swarm. The campaign describes more than 60 enemy types, including crawler swarms, diving bats, teleporting holograms, Burrowers that erupt beneath you, and Hoppers that dodge-roll away from rockets. Field Engineers retreat to deploy sentry turrets; other enemies include Rotary Gunners, Armored Titans, blade-dashing Reavers and acid-lobbing Spitters. Arena-specific foes include evil snowmen, skeleton cowboys, laser-packing aliens, glowing UFO drones, teleporting neon robots, ghost skeletons and fire-bats. The HIVEMIND is a floating brain mothership that sends drones from six ports until destroyed, while the JUGGERNAUT is an armored walking enemy that comes apart in pieces. Giant robot spiders, towering tripod walkers and colossal desert sand worms can turn whole levels into boss arenas.

Squad and upgrades

You can deploy up to four AI marines: Rook with a rifle, Viper with a scatter weapon, Hex with a minigun and Nova with a grenade launcher. They hold formation, call out the direction of threats, celebrate multi-kills and cover you when needed. If a squadmate goes down, hold E to drag them back into the fight. When your health drops below 30%, reinforcements arrive by parachute. The squad has over 500 voiced radio lines, including tactical chatter, boss warnings, arena hints, last stands, idle banter, jokes and death lines.

Between missions, spend DROP CREDITS on 22 permanent, multi-rank upgrades across three trees. Progress persists, and the upgrades support different builds, from a glass-cannon railgunner to a durable brawler or squad commander:

• Operator: Titan Blood, Nano Regen, Rift Shield, Phase Legs and Grav Boots.
• Arsenal: Kinetic Core, Gyro Servos, Munitions Rig, Warhead Lab, Arc Capacitor, Gore Fist and Shock Knuckles.
• Squad: Aegis Plate, Target Link, Battle Mesh, Combat Medic and Rapid Revive.
• Special abilities: unlock energy barricades, defensive shields, sentry turrets and more.

When your health falls below 30%, Rage Mode activates and increases your damage up to 1.75× as your health gets lower. Low health also triggers bullet time.
