Space Invaders is a classic arcade shooter where you blast descending aliens, guard your cannon with shields, and push for a new high score in crisp pixel action.
In Space Invaders, move the laser cannon left and right, take cover behind shields, and fire upward to clear each wave. Focus your shots to open a vertical lane and target the lowest row to halt a quick drop. Pace your fire so a new bullet leaves the cannon as the last one lands, since enemies speed up as their numbers fall. Save shields for later waves and reposition between barrages to stay safe.
Tip Stagger shots and leave one invader briefly while you reset your position before finishing the wave for better control.
