In Resogun, the smart bomb special attack is a critical gameplay feature that can significantly improve your chances of survival during intense moments. To activate this powerful attack, simply press the square button on your controller. When deployed, the smart bomb has the capability to clear the entire screen of enemies and their projectiles, making it invaluable during overwhelming enemy waves or challenging boss encounters.

When starting a level, players are equipped with a limited number of smart bombs, which necessitates strategic use throughout gameplay. It’s important to be mindful that deploying a smart bomb may result in a decrease in your final score bonus for that round. This scoring mechanic encourages players to use their bombs judiciously, weighing the immediate safety against the potential long-term score implications.

Additionally, players have the option to use the boost button (L1) to dash through enemies. This action can be tapped quickly to trigger a smaller area-effect attack at the end of the boost, which functions similarly to a smart bomb but with less potency. While this boost attack can help clear out immediate threats, it does not offer the comprehensive safety that a smart bomb provides.

Overall, smart bombs are an essential tool in Resogun, particularly when navigating through heavy enemy waves or during critical boss fights, where the eradication of active enemies and incoming projectiles can mean the difference between victory and defeat. Players must balance their aggression with strategy, utilizing bombs effectively to maximize their survival odds and overall score.
