## What is Holdout?

Build walls, bend the path and hold your keep! Holdout is a cozy idle tower defense game that plays offline, with no ads.

Monsters march from glowing portals toward your castle. Drop a wall and they reroute in real time. The path can't be fully blocked, so every wall is a choice: make the maze longer, line it with turrets, set traps on the road and turn each wave into a gauntlet.

WHY YOU'LL LOVE IT
• Real maze-building tower defense: walls reroute enemies, and a live path preview shows where they will walk
• Idle progress: mines keep earning gold while you're away, and your defenses keep fighting waves offline
• No ads, no pop-up videos, no energy timers
• Plays offline with no account (the shop needs an internet connection)

BUILD YOUR DEFENSE
• 5 turrets: Blaster, Skyshot anti-air, Mortar, Frost and Tesla, each with 3 levels
• 10 specializations: Sniper, Gatling, Flak, Railgun, Cluster, Howitzer, Blizzard, Shatter, Storm and Overload
• Walls, Gates you open and close on the fly, Ice Walls that chill and Bomb Walls that blast
• Traps on the path itself: Spikes, Glue, Brazier and Landmines
• Mines, War Totems, Radars and Banks to power your economy

HERO, SPELLS & POWER-UPS
Send your hero anywhere with a tap to fight ground and air enemies, level up during the run and unleash a War Cry that stuns monsters and rallies your turrets. Fireball, Lightning, Frost Nova and Mend recharge during battle; save Meteors, Deep Freeze, Overdrive, Gold Rush and Repair Kits for the waves that matter.

KNOW YOUR ENEMY
Swarms, armored Tanks, wall-ignoring Flyers, Healers, tunneling Diggers, Splitters, Shieldbearers and turret-jamming Bombers, plus giant bosses that summon minions, leap over walls or raise shields. A wave preview shows what's next.

A NEW ISLAND EVERY RUN
Random maps across 5 biomes: Sunny Meadow, Amber Woods, Misty Marsh, Frost Tundra and Windy Highlands, with rivers, mountains, forests, crystal deposits that double your mines, and snow, swamp and wind zones that slow enemies. Blizzards, fog, nightfall and thunderstorms change the fight.

GAME MODES
• Endless: survive as many waves as you can
• Campaign: 30 hand-tuned levels across 5 worlds, up to 3 stars each
• Daily Challenge: the same map for every player, every day
• Challenge Runs: stack modifiers like No Walls, Boss Rush or Glass Keep to multiply your stars

GROW STRONGER
• Permanent upgrade tree, hero talents and Ascension for lasting damage and gold bonuses
• Daily and weekly missions, a 7-day login gift and 24 achievements
• Monthly Battle Pass with a free reward track and a premium track unlocked with gems
• Lifetime stats and a bestiary of every monster you've defeated

MAKE IT YOURS
Hero and castle skins, turret sets, map themes, defeat effects and seasonal looks. Preview any item live on your island before buying, or grab themed sets and daily deals. Cosmetics are looks only and don't change gameplay.

MADE FOR PHONES AND TABLETS
One-handed portrait play, pan and pinch zoom, haptics, an adaptive soundtrack and a speed-up button. Progress is saved on your device, and a backup code moves it to a new phone. Play in English, Română, Deutsch, Español, Français or Português.

FAIR & FREE TO PLAY
Holdout is free to play with a few optional one-time purchases: gem packs, the Starter Pack and Premium Keeper. Premium Keeper adds 4× game speed, 24-hour offline earnings with double gold, 5 daily missions and the Golden Keep. No subscriptions, no loot boxes, no ads. Gems are also earned in-game from weekly missions, achievements, login gifts, the daily challenge and the Battle Pass free track. Gems, stars and other in-game items are virtual, have no real-world value and can't be exchanged for money.

GOOD TO KNOW
Holdout contains flashing lights and screen shake; your device's reduce-motion setting turns off the lightning flash and the shake. Take regular breaks. Questions? Reach us from Settings → Contact us.

Build. Reroute. Survive. How long can you hold out?
