The Cosmic Matrix in Marvel Cosmic Invasion contains 101 listed rewards: 30 hero palettes, 41 Nova Corps Files, 20 music tracks and 10 Arcade Mode modifiers, according to Selphie1999Gaming’s December 5, 2025 list. Below is the complete slot-by-slot index. The list is a third-party catalog, not an official published inventory; the official May 18, 2026 update says the text for cube #35 was changed, so check the current in-game description if it differs.
What the Cosmic Matrix unlocks
Cosmic Cubes reveal rewards in the Matrix. The listed rewards fall into four types, each serving a different purpose:
| Reward type | Count in Selphie1999Gaming’s 2025 list | What it offers |
|---|---|---|
| Hero palettes | 30 | Visual customization for playable heroes |
| Nova Corps Files | 41 | Character, enemy and faction lore entries |
| Music tracks | 20 | Music associated with menus, locations and fights |
| Arcade Mode modifiers | 10 | Rule changes that alter Arcade Mode gameplay |
Those category counts come from the third-party list; a TrueAchievements guide summary reports the same totals. Neither source is an official developer-published catalog. The game’s official site describes a 15-hero roster and a Cosmic Swap system that lets players pick two heroes for a level and switch between them instantly.
Every Cosmic Matrix reward by slot
The slot numbers and names below follow Selphie1999Gaming’s guide, published December 5, 2025. “Rocket Racoon” at slot 28 preserves the spelling in that source; the palette entries use “Rocket Raccoon.”

How many Cosmic Cubes do you need?
A TrueAchievements achievement-guide summary says 101 cubes are needed to complete the Matrix and describes cubes coming from level challenges, stage collectibles and team-level progression. That breakdown is attributed to the achievement guide rather than confirmed in the official game pages covered here; use the in-game progression screens for the requirements shown by your current build.

The December 2025 third-party list labels slot 35 “Double HP Enemies.” In its May 18, 2026 Steam announcement, the game’s official team said it updated the text for Cosmic Matrix cube #35. The announcement does not establish here that the reward itself changed, so treat the current in-game description as authoritative if its wording differs from the older list.
