About this game

Welcome to Space Defense Alpha. The galaxy is under attack, and you are the last line of defense in this fast-paced, no-nonsense arcade space shooter.

Built for players who love classic, quarter-munching action, Space Defense Alpha tests your reflexes against endless waves of alien invaders and relentless bullet-hell encounters. Dodge enemy fire, upgrade your ship on the fly, and fight for the number one spot on the leaderboard.

As always with KT Applications and Entertainment, there are no in app purchases, no hidden fees, no subscriptions. You buy it, you own it!

Key Features:

Endless Arcade Action: Survive increasingly difficult waves of alien swarms that scale in speed and aggression.

Epic Boss Fights: Face off against a massive, heavily armed Dreadnought boss every 5 levels.

Tactical Power-Ups: Turn the tide of battle with strategic drops, including Spread Shots, Rapid Fire upgrades, Energy Shields, and 2x Score Multipliers.

Dynamic Visuals & Feedback: Experience the action with particle explosions, a scrolling parallax starfield, dynamic ship damage states, and intense haptic screen-shake feedback.

Persistent Leaderboard: Compete against yourself. Space Defense Alpha tracks your Top 5 highest scores and updates your pilot rank in real-time as you play.

Pure Gameplay: No pausing. No distractions. Just you, your ship, and the high score.
