Why Choose the AF-91 Field Chemist Helmet?
What makes the AF-91 special compared to other helmets?
The helmet isn’t just for looks—it boosts your support abilities, especially for chemist-based builds. Its perks enhance the duration and effectiveness of buffs and deployables, which can be a game-changer in tough missions. Personally, I’ve found that pairing it with stamina-saving modules makes my team feel almost unstoppable, even during waves of heavy enemies.
How Does It Fit Into Support Builds?
Can you really make a full support-focused character with this helmet?
Absolutely. The AF-91 works best when you’re prioritizing utility over raw damage. Healing, buffing, and deploying traps or chemicals become smoother and more effective. In fact, it’s great for new players who want to contribute without constantly being in the thick of combat. Pro tip: keep an eye on your deployable cooldowns—this helmet slightly reduces downtime, which lets you maintain consistent support for your squad.
For players looking to gear up quickly, you might consider ways to buy Helldivers 2 medals to unlock additional helmet upgrades faster. This can give you a head start in equipping the AF-91 with the optimal perks for your support role.
What Are the Best Pairings?
Which armor and loadouts work best with the AF-91?
Pair it with light armor for increased mobility. Heavy armor can work too, but you might feel slower when darting around to assist teammates. As for weapons, keep a balance: a reliable ranged weapon for occasional combat and a support tool, like chemical sprayers or deployables, will make your helmet shine.
I usually pair the AF-91 with mid-tier gadgets and a mobility-focused secondary weapon. This lets me reposition quickly while keeping allies buffed. If you’re short on resources, platforms like U4GM can sometimes help you get the items you need, although I always recommend earning them naturally when possible—it just feels more rewarding.
