Boosters in Helldivers 2 are passive buffs that will be helpful for you and your teammates during a mission, and so need to be picked well. You can get benefits like better ammo/stims when you deploy, increased damage resistance, more stamina, better radar range, and more. Here are the best boosters to have in your build.
Which are the Best Boosters in Helldivers 2?
| Rank | Booster | Why It’s One of the Best | Situations Where It Shines |
| S-Tier | Vitality Enhancement | Gives a solid damage reduction from all sources and increases resistance to limb injuries. Improves survivability significantly. | Good in nearly every mission; especially useful on higher difficulties, against damage-heavy enemies, or when friendly fire or environmental hazards are common. |
| S-Tier | Stamina Enhancement | Boosts stamina capacity and recovery. Lets you sprint more, evade, and stay more active. | Very helpful for large or open maps, when traversing rough terrain, or when you need mobility (e.g. escaping swarms, moving between POIs). |
| A-Tier | Hellpod Space Optimization | You drop in with full ammo, grenades, and stims. So, you don’t need to go on an early hunt for resources or rely on resupply stratagems. | Particularly strong for early mission phases, solo play, or when support resupply is delayed. |
| A-Tier | Muscle Enhancement | Reduces movement penalties over challenging terrain (mud, snow, water, hills), which often slows you down in environmental hazards or when being chased. | Very useful on ice or snow planets, or any mission with areas that cause you to slow down. |
| B-Tier | UAV Recon Booster | Expands your radar range so you spot enemies, POIs, or objectives earlier. Useful for planning, avoiding ambushes, and farming. | If you like stealth, or are doing “find & complete” objectives, this is great. Less useful if combat is chaotic. |
| B-Tier | Increased Reinforcement Budget | Gives more reinforcements, so you get more backup when things go wrong. | Useful in especially tough operations, or when your squad is likely to take lots of casualties. |
| Situational / Premium | Experimental Infusion | Boosts stims to also provide speed and damage resistance (temporarily). This is strong when paired with good timing and use of stims. | Best in missions with high burst damage, or where grouping and timing matter. Also works well in emergency situations. |
| Situational | Flexible Reinforcement Budget | Reduces waiting time for reinforcements once your reinforcements are exhausted. Helps reduce downtime. | Best when reinforcement depletion is frequent (e.g., tough enemy waves). Worth considering once more basic boosters are covered. |
These were some of the best boosters to use in Helldivers 2. Based on your situation, level of teammates and requirements, you can choose the best option for your squad.
