About Redoubt: Castle Defense TD
Hold the gate through twenty-five pixel maps in five chapters. No energy meter, no gacha, no ads over the battlefield, and it all plays offline. One rule sets Redoubt apart: CALL WAVE. Send the next wave early and get paid for the risk. The third star on every map belongs to players who can hold the line at speed. HONEST DEFENSE • Every wave is scripted, not rolled. Wave 23 is the same wave 23 on your next run, so a loss is always on you and a win is always yours • No energy meter, no build timers, nothing to wait out • Every price is shown before you pay it, and selling a tower returns half of what you put into it • Built on the wrong pad? Undo your newest tower for a full refund, upgrade included, until it fires its first shot, 5 seconds of game time pass, or you build again • The banner stays on the menu screens; a full-screen ad may play when you change screens, never during a fight. Rewarded videos play only when you tap one A CAMPAIGN YOU CAN FINISH • Twenty-five maps in five chapters, from Meadow Road onward, each opened by winning the one before • Forked roads where the enemy alternates between the branches • Three towers, two upgrade paths each: Archer, Cannon, Frost • Enemies that demand different answers: footmen in numbers, goblins that run faster the more they are hurt, and armored imps whose armor softens every shot until the Archer's Bleed upgrade damages straight through it • Ten lives, 2× speed, and pause whenever you want to plan • Endless mode on any map you have earned two stars on, scaled by formula rather than chance THREE STARS FOR TEMPO Winning without calling a wave earns up to two stars. The third is for tempo: CALL WAVE sends the next wave early for bonus gold, the bonus shrinks the longer you wait out the countdown, and three stars go to players who earn enough of it while keeping at least eight lives. MAKE THE REDOUBT YOURS Tower colors and gate banners in the Shop's Cosmetics tab, plus banners you can only earn in play. Nothing changes the fight; it just looks like yours. PLAYS OFFLINE The campaign and Endless run entirely on your device. No account, no login, no game server. Your save stays on your iPhone or iPad. Only the optional ads and in-app purchases need a connection. English and Vietnamese, switchable in Settings, with text-size and reduced-motion options. Landscape, iPhone and iPad. Gems are optional. They buy a Continue for 50 gems when the gate is breached, the same second chance an optional rewarded video can give, and cosmetics in the Shop. Remove Ads is a one-off purchase: it turns off the banner and the full-screen ads, adds 300 gems once, and keeps rewarded videos available if you still want one.
