Undead Surge: Zombie Roguelike

Ten-minute runs, one thumb, a screen full of zombies. Fuse fire, frost and lightning into Supernova, Blizzard or Megavolt, then take on this week's Weekly challenge.

Survive the zombie horde with one thumb, an auto-aim rifle and spells you fuse into something bigger.

Undead Surge is a roguelike horde shooter made for portrait play. Steer with one thumb while your rifle picks its own targets. Every run lasts ten minutes: collect XP, choose a card at each level-up, and watch a few stray zombies grow into a flood of hundreds. Hold out until the clock runs down, then spend your gold and go again.

FUSE FIRE, FROST AND LIGHTNING • Nine spells across three schools: Chain Lightning, Meteor Strike, Frost Nova, Flame Aura, Storm Drone, Ball Lightning and more. • Pair two schools into Plasma Storm, Blizzard or Steam Cyclone, or push one school to Supernova, Megavolt or Absolute Zero. • 13 fusions in all, including upgraded Resonances and the three-school Meltdown.

FIVE RIFLE FORMS • Plasma Bolt, Scatter, Rail, Ricochet and Burst each change how every shot works. • Max a form's key mod and a boss chest evolves it.

A NEW BUILD EVERY RUN • 45 level-up cards: spells, rifle mods, powers, reactions, dash and Starfall techniques, and risky Gambits. • Elites drop chests, bosses drop better ones, and banishes keep unwanted cards out.

13 CHAPTERS, EACH WITH ITS OWN RULE • From Ember Crypt and Frost Hollow to Dead Line, Final Whistle Arena and Midnight Midway. • Every chapter changes the fight: erupting vents, black ice, trains clearing the tracks, dust whirlwinds, turning carousels and more. • Two bosses in every chapter. Read the telegraph, dodge the slam, bring them down.

MODES FOR SHORT AND LONG SESSIONS • Classic: survive ten minutes. Quick: the same run in five. • Endless: win, then choose your next Depth and keep going. • Threat Levels 1–10, then Custom Threat, for a harder climb. • Weekly challenge: a new twist each week, and everyone plays the same kit. • Boss Rush, Last Light, Custom Surge, featured challenges and 60 Expedition stages.

PROGRESS THAT STICKS • 24 talents with 10 alternates, 7 Survivors to play as, and a Codex of every card you find. • 37 achievements and 4 leaderboards on Game Center. • Daily missions and a login calendar that never resets.

PLAY YOUR WAY • Plays offline. No Wi-Fi needed to play a run. • No energy or stamina timers. • Close the app mid-run and pick up exactly where you left off. • Left-handed controls, text size up to 200%, three color-blind presets, Reduce motion, sliders for screen shake and flashes, an Assist option, and controller support.

Ads are optional rewarded videos, at most five a day, and they never play during a run. The shop sells hero looks, spell themes, gold packs, a milestone pass and early access to the side chapters. No loot boxes, no paid revives.
