Nivra

Command a high-tech armored battle tank and defend your frontline against relentless alien invaders under a star-filled cosmic sky in Nivra! Take absolute control of a powerful military vehicle locked in a high-stakes war for planetary survival. Roll across rugged terrains, aim your heavy cannon turret with absolute precision, and blast incoming enemy spacecraft and mechanical drones out of the air. Test your tactical shooting reflexes, dodge falling energy projectiles, and hold the line against massive alien boss ships!

Desktop Controls Press the A and D keys or the Left and Right Arrow keys on your keyboard to drive your battle tank smoothly backward and forward across the terrain layout. Move your Mouse cursor across the sky to aim your cannon turret, and click your Mouse Left-Click to fire explosive artillery shells at the target grids.

Mobile/Tablet Controls Tap and hold the virtual Left and Right Arrow buttons located on the bottom corner of the touchscreen interface to steer your moving vehicle. Tap and drag your finger anywhere on the upper screen area to calibrate your firing trajectory, then press the dedicated virtual Weapon icon to unleash rapid energy blasts.

Gameplay Rules & Objectives Your main objective is to eliminate all descending alien waves and floating mechanical threats before they crash into your tank or cross your base perimeter. Every hostile ship destroyed awards gold coins and combat upgrade points. Spend your gathered resources dynamically to upgrade your tank's armor plating, buy rapid-fire cannon barrels, and unlock powerful localized shield spells. If enemy fire or kamikaze drones completely deplete your vehicle's health pool to zero, the defense mission ends in a failure.

How to Win & Strategy Do not just park your tank in the center of the screen and fire blindly at random targets. It is highly recommended to stay on the move constantly between left and right boundaries to dodge falling projectiles naturally, while focusing your primary cannon fire entirely on the fastest moving scout ships first to prevent them from flanking your position early in the wave.
