Type words. Destroy aliens. Survive the invasion. LexInvaders turns typing into an arcade shooter. Letters fall from the sky, enemies close in, and every correct letter you collect builds the word that saves you. Complete words. Clear waves. Face boss sentences. The longer you survive, the faster the chaos becomes. Simple to learn. Hard to master. A real arcade challenge built around words. GAMEPLAY Pilot your ship and collect falling letters to spell the target word at the top of the screen. Every correct letter brings you closer to completing the word and clearing the wave. But be careful. Enemy blocks fall with the letters and cost you lives if you hit them. As you complete words, the game speeds up and the screen fills with even more chaos. Every decision matters. Accuracy, timing, and quick thinking are the key to survival. FEATURES • Four difficulty modes: Easy, Medium, Hard, and Challenge • Boss waves every five rounds with multi word sentences • Power ups including shields and hearts • Three life health system with mistake tracking • Tilt controls for intuitive movement (optional in settings) • Haptic feedback system (optional in settings) • Local high score tracking • Three music tracks and eight sound effects with separate volume controls • Game Center leaderboard support HOW TO PLAY Look at the target word at the top of the screen Shoot letters to collect them Correct letters cost one bullet, wrong letters cost three Complete the word to score points and speed up the game Avoid enemy blocks that cost lives Survive boss waves to earn big score bonuses TIPS Accuracy matters.

Complete words quickly to increase your score multiplier and survive longer. LexInvaders is built for players who enjoy word games, arcade challenges, and fast reflex gameplay. One time purchase. No ads. No subscriptions.
