While I haven't played CDDA, I can talk a little bit about what makes Cogmind unique compared to the rest of the genre.
Cogmind is classless - you always start the game with the same set of items and abilities. Your build is defined by what parts you find or salvage from enemies, as well as certain events that give you permanent upgrades.
The most obvious difference is the combat system: each and every item you equip can be damaged and destroyed. Items also have a 'coverage' statistic which is proportional to how likely the item is to absorb a shot. For instance, armour in Cogmind isn't really special under this system - it's just an item with high health and coverage.
Cogmind is also mostly based on ranged combat, though melee is an option for both you and enemies. Therefore, the tactics you must use are slightly different.
