Beginner's Guide

When starting your adventure, focus on surviving each wave rather than rushing through enemies. Learn how projectiles move, collect every available reward, and spend your coins on permanent upgrades before purchasing cosmetic items.

Each completed wave lets you choose one of several temporary abilities. Selecting upgrades that complement each other creates a much stronger build for later stages.

Best Tips for Success

Upgrade Permanent Talents First

Permanent upgrades improve every future run, making progression much smoother.

Keep Moving

Enemy projectiles become much easier to dodge if you stay in constant motion.

Build Around One Strategy

Instead of choosing random abilities, focus on increasing either attack power, attack speed, health, or special abilities.

Unlock New Heroes

Different marine heroes offer unique strengths. Try several characters to discover which one best matches your play style.

Equip Better Gear

Armor, weapons, and equipment provide significant improvements during difficult stages.

Save Powerful Skills for Bosses

Boss battles are much easier if your strongest abilities are available when the fight begins.

Advanced Strategies

• Memorize boss attack patterns before attacking aggressively.
• Open reward chests whenever you earn enough keys.
• Upgrade both offense and defense for balanced progression.
• Replay earlier stages to collect additional coins and equipment.
• Pair your favorite hero with allies that complement their strengths.
• Continue improving talents even after unlocking stronger characters.
