Top games 2K15


Batman: Arkham Knight :-

The final game in the Arkham series, Arkham Knight is the first new-gen game in Rocksteady’s incredible foray into the Batman universe. It’s also the first time you can drive the Batmobile. It looks amazing, and makes me want to play through all the Arkham games again ahead of time. 


  There aren’t many games on this list that pique my hype as much as Bloodbornethe spiritual successor to From Software’s Souls games. This time around, the game is set in a dark, Gothic world filled with shambling villagers and massive werewolves. The combat is fast and ferocious, and new gameplay elements such as randomly generated dungeons promise to greatly change up a familiar formula, while still keeping the same, distinctive sense of challenge and despair.



 Another Xbox One exclusive, I’m of the mind that you can’t really go wrong with Platinum Games, the developer responsible for games like Devil May Cry, Bayonetta, and Metal Gear Rising: Revengeance. This time around, action-game master Hideki Kamiya brings us a game world populated by massive dragons, and a fighting game that sounds little like his previous work. After the brilliant Bayonetta 2 and charming Wonderful 101, hype is basically a Platinum Games default setting. Scalebound looks very cool. 







Heroes of the Storm:-

It wasn’t going to be long until Blizzard entered the MOBA fray, and Heroes of the Storm is their stab at taking on Dota and League of Legends. Yet this 5v5 arena game isn’t just another Dota clone. Instead Blizzard have made a game that is vastly more accessible than your regular MOBA, whilst still tightly holding on to the core characteristics of the genre such as complex heroes and memorising skill sets.
