Diep.io vs N.O.V.A. 1
Diep.io
Diep.io is a fun tank-like IO game where players play as pencil-drawn tanks on a piece of white (and sometimes gridded) paper filled with other hostile tanks as well as a variety of obstacles and Polygons. Shooting at Polygons and other players will earn you points to level up your tank to the next tier, unlocking a wide range of upgrades (or "classes" as the game calls them). At frequent intervals, AI-controlled bosses will be spawned allowing players to work somewhat cooperatively to earn a ton of experience points.Many players are calling out Diep.io as being a clone of the previously popular Tank.io (not sure what happened to Tank.io though), but considering that it's currently the last game standing, I guess it's safe to say that new players will never know about Tank.io but will instead be able to enjoy its legacy through Diep.io.
N.O.V.A. 1
N.O.V.A. 1 is set in a futuristic time period where Earth had became unsustainable to life. Thankfully, humanity has already created huge artificial satellites for people to live on and in their defense, N.O.V.A., the Near Orbit Vanguard Alliance, was born. However, when the aggressive alien race called Judgers showed their intention to wipe out humanity, retired veteran N.O.V.A. marine, Kal Wardin, was forced back into active duty in mankind's all-out war for survival against the Judgers. Aside from an epic campaign, the game also provides multiplayer matches, a worldwide leaderboard to rank its players, and up to 6 unique weapons to play with.N.O.V.A. 1 took the world by storm with its enigmatic hero, an epic "save humanity" storyline as well as brilliant graphics that just compliments the game's sci-fi theme. Although this game is no longer available, you can grab its latest installment, N.O.V.A. 3, or pick another game from our list of alternative games.
