Double Dragon Neon (PC version) is a very hard game to review. On one hand the gameplay itself is varied, and offers more ways to defeat enemies than have ever been possible in the franchise (Super Double Dragon or Battletoads/Double Dragon Ultimate Team). Wayforward defintely has its heart in the right place. On the other hand, the game is frustrating to play for all the wrong reasons and will probably turn away potential players.
For what it gets right, Double Dragon Neon is a very stylish nod to the 1980's and all the cheesiness bravado that was found in arcade video games during this era. DD Neon employs an experience system and offers shops to spend money/ore you collect in levels, much like the Game Boy Advance version of TMNT via UbiSoft. The PC version offers various resolutions, and offers very smooth 60 fps beautiful cell shaded animation and graphics. The soundtrack here is probably the best original score for its release back in 2012, and offers throwbacks to the 80's with very catchy lyrics accompanied by synthesizers and drum machine beats. The game also is very leniant with how combos work, allowing for mid-air catches and throws while allowing for moves that involve running or crouching. Overall, the combat (and screen clearing attacks) are more reminscent to Streets of Rage than classic Double Dragon (or its many sequels or spinoffs).
For what the game gets wrong is heartbreaking. Billy and Jimmy Lee are incredibly sluggish when controlling around, and its made more frustrating when you have to dodge telegraphed boss attacks that can (and will) juggle you in the air or in the corner; effectively draining your health and losing a precious life (lose all your lives and restart the entire mission over). There are sections in the end where its uncommon to fall off cliffs because you weren't fast enough to dodge a whirlwind attack and lose precious health (losing lives would have been much worse).
The coop aspect makes more sense when playing local coop, because the coop here is very weak especially in this "definitive edition" PC port. Stealing lives, sharing diet coke health pickups, and allowing the other player to collect 1-ups is essential for this very hard game (even when using the 'training wheels' tape)....so its too bad none of this can be done effectively in the PC port. The PC version supports no text or voice chat whatsoever, so playing with a random person in Steam matchmaking is hit or miss.
When joining as a client, it's no help that the game still has issues with latency (overall performance on the zombie forest stage is horrible even in single player)...online play is functional....but reduces frame rates to about 25ish with all the stuttering and teleporting (online code as of 7/2/14).
Abstration Games have pretty much done little work to get this port to the PC, as evident in the very confusing key assigning in the options (good luck seeing that its Tab key to even get in there with keyboard controls) or the obtuse indicator for reviving your coop buddy via rewinding his tape (good luck seeing that its done with your throw key). Save yourself the frustration and don't bother playing this game with a keyboard, because the devs clearly just pushed this out the door with an Xbox controller in mind.
Overall, this game just barely wins a recommendation from me clearly on the presentation and solid combat while playing single player or local coop. Game offers a lot of little fun things to do with a coop partner (one player beatboxes and the other breakdances), and its clearly meant as a local coop game. The problems from the console release are here for the most part, and I can't really recommend this version of the game if you want to play online (while your online partner is very far away or has a subpar internet connection). If anything, pick this game up when it goes on Steam sale.
