The Infiltrator is a side-scrolling shoot-'em-up inspired by classic arcade games like Gradius and Darius. You'll face relentless waves of enemy ships while dodging a constant barrage of incoming fire. Fortunately, you're equipped with rapid-fire missiles capable of destroying enemy ships. However, your opponents are fast and aggressive, so success depends on firing accurately while staying on the move. The game features four increasingly challenging levels. The final stage is the toughest, introducing small, circular enemy ships that move at high speed and are much harder to hit. Complete all four levels to finish the game. If you're aiming for a place on the high score table, be prepared for a challenge—the preset high scores are set high, and you'll likely need to reach at least the fourth level to earn a spot.
