Space Defense: Guard Heroes

About

You're defending a base against endless waves of alien enemies by placing and upgrading towers along their approach while commanding a squad of heroes on the ground. The tension comes from managing limited resources across a whole map — every tower you upgrade is a tower you didn't build somewhere else. It's classic tower-defense strategy dressed up in a sci-fi invasion, with enough hero and upgrade choices to make each defense line feel like your own.

Controls

Tap a build slot to place or upgrade a tower, and tap a hero to direct them toward oncoming enemies.

Tips

• Push a few towers to a strong upgrade tier before spreading resources thin across the whole map — several hard-hitting towers usually beat many weak ones.
• Scout the enemy path before you build; a tower placed after the alien route has already curved past does nothing for that wave.
