Dead Cells is a combination of two different game genres Metroidvania’s and Roguelite’s meaning it has the large maps and exploration of Metroidvania’s and the permadeath and randomness of Roguelike games RougeVania as we like to call it. Dead cells build from the Metroidvanias that came before it, go off and explore the large map to get access to hidden areas to get bonuses to help you on your run. Dying is part of the learning process the more you play the game the more you get better you will also unlock permanent buffs like weapon upgrades on your runs.  

• Dead cells have a challenging but fair combat system, gather an arsenal of weapons and spells each with unique gameplay effects, you can also dodge roll like other souls like games if the enemy is overwhelming you.
• Explore the procedurally generated maps, take a moment and admire the view, choose which biomes you want to go to Ossuary, Sewers, or Ramparts? Once you finish a biome you get to unlock a permanent Upgrade that stays with you even after you die, these abilities can also open new paths to reach your objective.
• Overall Dead cells have 25 total levels/biomes, but you will not go through them all in a single run you will go through at least 6 levels/biomes, not including boss areas, 90 weapons and skills, and hours of unadulterated fun.

Reviews

Dead Cells is a masterpiece. It is the marriage and apotheosis of decades of Metroidvania design and the surging popularity of difficult Roguelike games. It is exquisite in all ways. It looks phenomenal. It plays like a dream. It makes you want to keep coming back even when you fail.

There aren’t too many good roguelike action platformers out there, but those that are really great are even fewer. Dead Cells is clearly part of the last group, a rare breed of games that get you addicted by killing you over and over again, but masterfully pulling you back in every time.
