The main objectives include defeating waves of alien enemies, completing missions, and upgrading your weapons and abilities to survive tougher levels.

To upgrade weapons, collect in-game currency and resources from defeated enemies. Access the upgrade menu in the main interface and select the weapon you want to enhance.

Using strategic positioning, upgrading your character’s abilities, and coordinating your attacks during boss fights can significantly improve your chances of defeating them.

Resource management is crucial. Focus on collecting energy packs and ammunition while avoiding unnecessary spending on upgrades until you are well-equipped. Prioritize upgrades that enhance your survivability.

Handling enemy waves involves a combination of movement and firepower. Stay mobile to avoid damage, use cover effectively, and target larger enemies first. Here are some steps to follow: 1. Identify the strongest enemies. 2. Use area-of-effect weapons to deal with groups. 3. Keep moving to avoid getting surrounded. 4. Utilize power-ups strategically to gain an advantage.
