"Mastering Weapon Unlocks and Strategies in Helldivers 2"

In Helldivers 2, all weapons have armor piercing rounds, but most can only penetrate light armor, making them effective against low-tiered enemies but weak against heavily armored foes. The game requires strategic use of support weapons to expose weak spots on heavily armored enemies before using primary weapons for critical damage. Certain weapons like the Breaker, R-63 Diligence, and Railgun are recommended for their armor-piercing capabilities, while it's advised to avoid using primary weapons against heavily armored enemies without first exposing their weak spots.
