Marvel Cosmic Invasion is an arcade-style beat 'em up featuring an incredible array of characters spanning Marvel's golden eras.

In Marvel Cosmic Invasion, the immortal Super Villain Annihilus has launched an unprecedented attack across the galaxy, threatening all life as we know it. Super Heroes both Earth-born and cosmic must now join forces in a star-spanning adventure against the deadly Annihilation Wave. Brawl through the streets of New York City all the way to the depths of the Negative Zone to foil Annihilus’ vow to spread death across the cosmos in classically inspired side-scrolling combat.

Choose and control your own team of two characters while tagging between them mid-fight with the innovative Cosmic Swap system, capitalizing on distinct superpowers and special attacks to create unique team-ups and dish out devastating damage. Unlock stellar powerups and rewards while experimenting with different duos and bash through a fantastic collection of locales and nemeses from the Marvel universe. Marvel Cosmic Invasion’s action includes a range of accessibility features, empowering the whole family to be Super Heroes (or villains), and supports four-player drop-in/drop-out local and online co-op with crossplay.

After setting the bar for arcade-inspired beat ‘em ups with the acclaimed, multimillion-selling smash hit Teenage Mutant Ninja Turtles: Shredder’s Revenge, Dotemu and Tribute Games modernize the timeless fun of brawlers with exciting tag-team fighting and a multi-era celebration of the most iconic comic book universe in Marvel Cosmic Invasion. A masterful pixel art style perfectly embodies the spirit of classic Marvel character designs resulting in thrilling action that’d look right at home in an arcade cabinet.


Doctor Doom’s latest plan will be the galaxy’s downfall… unless you scrap his next invention in an all-new game mode arriving via Marvel Cosmic Invasion: The Siege of Castle Doom.

In the Castle Doom mode’s run-based action, you must break through the defenses of Victor von Doom’s foreboding stronghold before he’s able to activate the Cosmic Inductor. This flawed weapon was designed to thwart Annihilus, but is destined to end the cosmos as we know it.

Each encounter you survive will charge the Stabilizer, a genius creation of The Fantastic Four’s Reed Richards that’s capable of foiling his oldest nemesis’ newest plan. Gather Battery Cells and complete challenges to earn defense, damage or tactical upgrades from a collection of 12 different perks, but keep your wits about you: failing challenges will debuff your fighters, and Doctor Doom has set traps anticipating your arrival … Thankfully, successful runs will help permanently unlock new equipment and events from Reed’s Lab, as well as modifiers that can deepen the challenge and potential rewards available in future attempts.

Choose your path through the castle’s winding routes and thoughtfully select buffs to alter your combat abilities to become an unstoppable powerhouse. You’ll need all the might you can muster to persevere, and the castle’s deadly Doom Bots are allied with bosses returning from the base game to settle scores with you.

Whichever path you take and perks you choose, be sure to reach Victor von Doom before the ominous Siege Gauge is full; the castle’s forces grow in power as the gauge fills, but your heroic efforts will end instantly if the gauge completely fills before your climatic showdown.

In addition to Castle Doom’s distinct new challenge, Marvel Cosmic Invasion: The Siege of Castle Doom’s celebration of MARVEL’s golden eras also includes the debut of The Fantastic Four’s Susan Storm as well as Doctor Doom as playable characters, new unlockable color palettes for all playable Super Heroes who successfully defeat Doctor Doom, as well as electrifying original musical tracks from renowned composer Tee Lopes.
