How it works
• Bunkers are made of destructible blocks.
• Aliens march as a group, then drop and reverse at edges.
• Alien shots pick random alive aliens.
Scoring
Top aliens are worth more. Each alien is worth 30/20/10 points by row.
Space Invaders
Shoot the invaders. Defend the cannon. Survive.

Tip: clear a row quickly—alien fire increases as numbers drop.
