Unfortunately, Aliens: Fireteam Elite launched with a number of issues, both from bugs and technical issues, to flaws resulting from core concepts D2R Items. Character customization was limited and lacked variety, while both combat and levels felt repetitive due to reused environments and enemies, undermining the game's push for replayability.

Bugs ranged from odd audio and visual issues to more of the game breaking variety preventing ammo from being restocked or interacting with anything in the environment. While the game seemed strong on paper, it ultimately left a lot to be desired.

Back 4 Blood
With the original developer that worked on Left 4 Dead, Turtle Rock Studios, returning to the genre that it helped make popular, Back 4 Blood instantly became a highly anticipated title. Retaining a similar formula where a team of four navigate through levels overrun with undead, Back 4 Blood utilizes a card system to modify gameplay elements from enhancements, bonuses, to corruption cards which increase the difficulty. While Back 4 Blood experienced huge success at launch, many fans found the overall experience to be less than optimal.

Turtle Rock has admitted that it was tuned to be too difficult and spawn spawned special Ridden enemies far more often than intended. The game's Swarm mode, which introduces PvP into the game, feels like a missed opportunity D2R ladder items buy, while the community was hoping for more of a Left 4 Dead Versus mode.
