Introduction to Secret Avengers

Marvel Strike Force Maria Hill and Sam, alongside Sharon Carter, make up the core trio of the Secret Avengers team in Marvel Strike Force. This squad has historically been a valuable and well-rounded investment for many players due to their strong synergy, reliable performance, and adaptability across various game modes, including Raids, War, and certain Cosmic Crucible matchups. Each member brings unique strengths that complement one another—Maria Hill provides consistent healing and summon support, Captain America (Sam Wilson) offers valuable barrier generation and turn meter manipulation, while Sharon Carter delivers crowd control and defense-reducing abilities. Together, they form a balanced team capable of handling a wide range of encounters.
In earlier phases of the game’s meta, the Secret Avengers were considered a high-priority investment, both for their standalone power and for their synergy with characters like Kestrel and Nick Fury. They were commonly slotted into hybrid teams, thanks to their individual utility and low reliance on very specific team compositions. This made them a go-to option for players looking to maximize value from a limited roster.
However, as Marvel Strike Force has progressed and newer teams have been introduced with higher damage ceilings, better speed manipulation, or specialized counters to key threats, the Secret Avengers have seen a decline in overall relevance. They are no longer considered a top-tier or must-invest team in the current meta, especially for players focusing on late-game content or climbing competitive modes. Modern teams now tend to offer stronger performance in specific modes like Incursion Raids or Alliance War, pushing older squads like the Secret Avengers further down the priority list.
Despite this decline in prominence, the Secret Avengers remain relatively inexpensive to build compared to newer teams that often require harder-to-obtain gear or characters. They still provide dependable utility for mid-tier players or those looking to round out their roster without committing to high-cost investments. For players who already have this trio unlocked and leveled, they can continue to serve a meaningful role, especially in modes where flexibility and team reuse are important. While they may no longer define the meta, their functionality and ease of use keep them relevant in many scenarios across Marvel Strike Force.
Team Utility and Compositions

The Secret Avengers team in Marvel Strike Force is primarily designed for Raid content, with many of their abilities providing enhanced effects specifically in that game mode. Their performance was particularly strong in Doom and Ultimus Raids, where their synergy, survivability, and utility made them a top-tier choice. However, their overall effectiveness declined sharply with the introduction of Incursion Raids, which demand more specialized team compositions and stronger power scaling. As a result, the Secret Avengers are generally not considered viable for Incursion Raid content.
Despite this shift, individual members of the team, especially Maria Hill and Captain America (Sam Wilson), still offer solid utility in other areas of the game. Both are frequently used in Dark Dimension due to their supportive roles—Sam provides barrier and energy control, while Maria contributes healing and summon-based utility, which can help extend survivability in prolonged fights. Their strengths make them effective standalone additions in rosters looking to fill key support or control roles.
For players seeking to maximize the effectiveness of the Secret Avengers trio—Sam Wilson, Sharon Carter, and Maria Hill—the team benefits greatly from being paired with two strong “plug-and-play” characters. Historically, Shang-Chi and Kestrel have been popular and effective additions, especially in Doom Raid environments, where their synergy contributed to strong clear times and consistent success. In Alliance War, the trio combined with Kestrel has proven capable of beating many punch-across teams, including Hero for Hire. However, they typically fall short against higher-tier teams such as Infinity Watch.
Outside of traditional Secret Avengers setups, the characters can also function well in flexible team combinations. Captain America (Sam Wilson) has been used effectively on War Defense with Mercenaries, where his barrier and energy manipulation can disrupt enemy strategies, particularly against teams like Skill Military and X-Force. Maria Hill, when paired with Kestrel on offense, becomes especially useful as her summons can repeatedly trigger Kestrel’s passive attacks and act as buffer units to absorb incoming damage.
Some players also build hybrid teams around the Secret Avengers core, adding characters like Nick Fury and Kestrel to take advantage of summon-heavy mechanics. The summons from both Hill and Fury provide multiple triggers for Kestrel’s passive ability, significantly boosting team damage and control. When Fury is not available, characters such as Baron Zemo or Agent Coulson have been used as alternative fifth members, providing control or utility depending on the game mode. Overall, while the Secret Avengers are no longer top-tier in all content, their adaptability and individual strengths keep them relevant in various team configurations throughout Marvel Strike Force.
Captain America (Sam Wilson) Details
Captain America (Sam Wilson) in Marvel Strike Force is a Hero, Global, Skill, Protector character and a key member of the Secret Avengers. He brings a strong mix of survivability, team utility, and speed control that makes him effective across a broad range of game modes. He is consistently rated highly in Arena, Alliance War (both Offense and Defense), Blitz, Real-Time Arena, Raid, Dark Dimension, and Cosmic Crucible, making him one of the more versatile protectors in the game.
His ISO-8 class can be tailored to fit different team needs. Fortifier enhances his natural durability by boosting barrier generation and survivability, making it ideal for his role as a front-line tank. Healer is another viable choice, as he takes frequent turns and can contribute to team sustain. Skirmisher helps with clearing positive effects using his Basic and applies Vulnerability for follow-up attacks. Raider can also be considered in setups where his Ultimate hits multiple targets, increasing crit-related benefits for the team.
When upgrading his T4 abilities, his Ultimate and Special are top priorities. The Ultimate deals more damage and fills the Speed Bar for himself and Liberty/Skill allies by 10% per enemy remaining, which can significantly shift turn order in your favor. His Special becomes much more effective with T4 investment, increasing Taunt duration to two turns, providing three Deflects, and generating energy for non-summoned allies. These upgrades help improve both team survivability and ability cycling. The Passive is also a strong upgrade, boosting his Block Amount by 20%, further reinforcing his tank role. While not as critical, his Basic also benefits from a T4 to more reliably remove buffs and deal increased damage.
Captain America (Sam Wilson)’s core mechanics center around maintaining Taunt while stacked with Deflects, which he gains through his Special and Basic. Once the Deflects expire, he loses Taunt but gains two Regenerations, allowing him to recover health passively. While Deflects are active, he gains +300% Resistance, making him significantly harder to debuff. He also passively boosts team survivability by increasing Max Health by 40%, a substantial stat increase that supports all allies. His Basic can also generate Deflects, helping to maintain uptime on key buffs.
In combat, he can open with either his Ultimate or Special, depending on the enemy team. Against faster opponents or in tight timing scenarios, using his Ultimate first can provide critical Speed Bar advantage. His flexibility in turn order and ability cycling gives him strong tactical value in Raid, War, and Crucible settings.
He is farmable from Heroes 3-3, Doom 2-6, and Milestone III Orbs, making him relatively accessible. While many players have him at 3 Red Stars due to orb luck or early availability, he performs well at lower star levels. However, if resources allow, upgrading him—and the rest of the Secret Avengers—to 5 Red Stars is recommended, especially if you plan to use them in endgame content. Maximizing his Red Stars is more important when preparing for Dark Dimension, where survivability and overall power scaling become more critical. Captain America (Sam Wilson) remains a valuable and adaptable character in Marvel Strike Force, particularly when used as part of the Secret Avengers or in hybrid team compositions that benefit from his strong protector role and speed control.
Maria Hill Details

Maria Hill is a Hero, Global, Skill, Support character affiliated with both S.H.I.E.L.D. and the Secret Avengers in Marvel Strike Force. She plays a critical support role, offering strong healing, team cleansing, and minion summoning, which collectively bolster team survivability and synergy. She consistently receives high ratings across all major game modes, including Arena, Alliance War (both Offense and Defense), Blitz, Real-Time Arena, Raid, Dark Dimension, and Cosmic Crucible, making her a reliable utility character in a wide range of content.
Her ISO-8 class is best set as Healer, which is the only truly viable option to maximize her potential. Given how frequently she takes turns and how central her role is in maintaining team health, this ISO-8 choice directly reinforces her effectiveness in sustaining allies during prolonged fights.
When it comes to T4 ability upgrades, her Ultimate and Passive should be prioritized. Her Ultimate gains a significant boost by clearing all negative effects from Avenger and Skill allies instead of just one, while also delivering solid area healing and applying Deflects to herself and all Secret Avengers. This ability is essential for team cleansing, especially in Raid and War scenarios. Her Passive is another essential upgrade, increasing her healing by 15% and enabling additional healing triggers when team members block, which synergizes well with Captain America (Sam Wilson)’s high block rate and Deflect generation. Her Basic is recommended for more consistent healing, as it always applies Deflect to the most injured ally and adds Regeneration if they are a Secret Avenger, increasing her overall healing throughput. Her Special is also a strong upgrade, boosting the number of summoned S.H.I.E.L.D. Troopers from two to three. These summons serve as extra targets for enemies, provide bonus damage, and can trigger Kestrel’s passive, making them useful both offensively and defensively.
Maria Hill’s core mechanics revolve around providing team support through cleansing, healing, and summoning. She excels at keeping the team in fighting shape, especially in Raid content where her abilities gain additional potency. Her Ultimate not only heals but also provides 3 Deflects to all Secret Avengers, directly enhancing Captain America (Sam Wilson)’s tanking potential. Her Basic and Passive offer consistent support by directing healing and buffs to allies in need, and her summons add pressure by distracting enemies and applying additional damage. She also provides a team-wide Resistance bonus of 40%, which increases to 80% in Raids, further reinforcing her role as a Raid-focused support unit.
In combat, her ability sequence is relatively straightforward—start with her Special to summon troopers and follow with her Ultimate to cleanse and heal. Proper target selection is important when using the Special, as minions will attack the chosen enemy immediately upon spawning. Holding her Ultimate for a key moment can be critical, especially when anticipating a wave of debuffs or teamwide damage.
Maria Hill is farmable from Heroes Hard Mode 2-6, the Blitz Store, and Milestone III Orbs, making her one of the more accessible support characters. Like her teammates, many players report having her at 3 Red Stars or lower, but if resources allow, promoting her to 5 Red Stars with Silver Promotion Credits is worth considering, particularly for players aiming to use her in Dark Dimension or other high-difficulty content. Her reliability and utility remain strong assets in any roster, especially when paired with her Secret Avengers teammates or slotted into hybrid compositions in Marvel Strike Force.
