Battlefield 2 vs N.O.V.A. Legacy
Battlefield 2
Battlefield 2 is one of the Battlefield classics and rightly so. The game lets you play as a soldier in one of the three major military superpowers: the United States, the Chinese or the newly-formed Middle East Coalition. Players will have access to a wide range of weaponry to do battle with as well as a variety of vehicles. Similar to the original game, the game has a large-scale multiplayer mode - the hallmark of any game from the main Battlefield series - that can accomodate up to 64 players on a single map.With more weapons and vehicles for you to play with, Battlefield 2 is a pretty nice sequel to the Battlefield franchise. However, considering that it has not yet been reworked, unlike the first Battlefield, and that currently, there is no way you can purchase the game unless you get the hard copy off eBay or a similar site, you might be better off buying any of the other Battlefield games.
N.O.V.A. Legacy
N.O.V.A. Legacy is among the best sci-fi-themed MMOFPS game on mobile of all time and it has inspired a popular new franchise, N.O.V.A. as well. In this game, you play as Kal Wardin, a veteran N.O.V.A. marine, who have been drafted once again into the Colonial Administration forces to fight against the alien invaders that threaten the whole of humanity. The game provides players with a wide variety of PvE game modes to play in, including an offline story mode, Shadow Missions where you get to fight aliens on a limited time battlefield, and Special Ops that pits you against various unique alien formations.N.O.V.A. Legacy also has a multiplayer mode that will allow you fight against other human players in exciting 4-vs-4 team deathmatches or the last-person-stading deathmatch. In addition to crafting and upgrading your weapons, customizing your character's Mobile Armored Suit is very easy and in-depth as well. You can add Cores to give yourself some nice bonuses to supercharge your gameplay.
When it comes to multiplayer shooters on the mobile platform, there are only a few that can go as far as to claim that it plays just like a console game - this game is definitely one of them. Granted that the graphics isn't as great as marketed, but the gameplay is amazing and you even get an offline story-based missions on this free-to-play app! It is as good as it gets!
