Gameplay Overview
MARVEL Cosmic Invasion is a classic side-scrolling, four-player drop-in co-op beat'em up, but it introduces the unique Cosmic-Swap tag-team mechanic which radically changes the flow of combat. Teams consist of two heroes, allowing players to instantly switch characters to maximize combo potential, strategically avoid damage, or deploy powerful assist attacks.
Starter Tips for Beginners
- Familiarize yourself with only a few characters first: the 15 heroes have very different fighting styles that may not be suited to your playstyle. Find at least two you find yourself confident with, and focus on learning the intricacies of their movesets. No matter the pair you pick for each stage, you won't miss any story content, and you can eventually return to complete stages to clear Challenges requires specific characters later on.
- Use Cosmic-Swap to Escape: One of the most important technique to use is using Cosmic-Swap (L1/LB/L) to get out of trouble. If you are cornered, about to be hit by a boss attack, or immobilized by a grab, a quick swap tags in your partner, letting them get out of the fight to avoid additional damage and restore the red portion of their HP gauge.
- Farm Level 5 ASAP: The Passive Skill learned at Level 5 is crucial for most characters. Focus on replaying the first few Campaign stages a couple of times to hit Level 5 on your favorite heroes quickly. This can be a massive help to clear the most challenging stages of the campaign.
Play Modes
The game features two main modes, designed for different types of players:
- Campaign Mode: Navigate a map and progress through 15 stages, each featuring unique hazards, a final boss, and three optional Challenges to complete. Completing certain stages unlocks new characters.
- Classic Arcade Mode: A true throwback experience with no continues, replicating the difficulty and high-score pressure of an arcade cabinet. The ultimate test of mastery.

Moveset Fundamentals
All heroes share a common control scheme, but their execution and effect vary widely. Understanding these core inputs is the first step to improve at the game.
| Input | Description |
|---|---|
| Square/X/Y (Combo) | Basic combo string, often ending in a launcher or knockdown. |
| Triangle/Y/X (Special) | Unique attack utilizing self-regenerating resources or unique weapons. |
| Circle/B/A (Defense) | Used for either a Block (Captain America, Cosmic Ghost Rider, Iron Man, Nova, Phoenix, She-Hulk, Silver Surfer, Venom) or a Dodge/Evade (Beta Ray Bill, Black Panther, Phyla-Vell, Rocket Raccoon, Spider-Man, Storm, Wolverine). |
| Cross/A/B + Square/X/Y | Rising attack used to launch enemies into the air for subsequent aerial combos. (Beta Ray Bill, Black Panther, Captain America, Cosmic Ghost Rider, Iron Man, Phyla-Vell, Silver Surfer, Wolverine only) |
| Forward x2 + Square/X/Y | Rushing attack with a wide hitbox best used as a gap-closer and crowd-control move, perfect for escaping the corner, and hitting multiple enemies at once. |
| R1/RB/R (Ultimate) | Focus-consuming attack with full invincibility, perfect for massive damage and managing critical danger. |
Core Mechanic: The Cosmic-Swap
The Cosmic-Swap is the heart of the combat system. Pressing L1/LB/L allows for an immediate character switch (tag-in/tag-out) using a small portion of the Focus gauge. This is your primary tool for escaping hit-stun, managing incoming damage, and extending combos.
The mechanic deepens significantly with the assist system:
- Assist Attack: Hold L1/LB/L and press an attack button to deploy your inactive character for combo attacks, aerial attacks, rushing attacks and, special attacks (Spider-Man's Webbings, Cosmic Ghost Rider Cosmic Blast and so on).
- Dual Ultimate: If enough Focus is saved, you can unleash a powerful combination attack with both characters simultaneously by holding L1/LB/L and pressing R1/RB/R.
A deep-dive guide detailing the absolute best Cosmic-Swap assist attack you shouldn't sleep on is currently in the works. It will be live soon.
