One star, due to the lack of dev oversight and the overrun of players who cheat/hack/mod the game gets 1 star and even that is more generous than it deserves.
You will have maybe 1 in 10 matches where somebody isn't cheating in some way. From infinite health, to teleporting, to impossible move speed. If you haven't started I suggest you dont bother.
Starter guns are garbage and you'll get maybe 1 kill per match using them no matter how much skill you have at fps games. Better guns take around 20 hours each to grind for. To get all the parts to customize them after getting a gun you want will take about 8 hours per part (6 parts) totaling over 48 hours of grinding just to get the most out of your nice new gun. Oh and it goes the same length for your sidearm.
Then get ready, you will need to grind for armor for 48 to 96 hours to get 4 parts. Then another upwards of 250 hours of grinding for items like grenades mines ect. Followed by another 20 for a fifth consumable like reviving teamates, to a roit shield, to a self healing machine.
Congratulations after nearly 500 hours of grinding you have a single load out of 2 guns, 4 armor, 5 consumables. Now get ready to finally sit back relax and enjoy the game. Unless you want to grind for you second or third load out. Otherwise sit back, and enjoy.
And in the event you wanna just buy a fancy elite loadout get ready to drop more than the price of a new game. To buy a full loadout of gear, and customize it will cost you more than 60 bucks or a whole new game.
Best advice, find a different game to play, any game. Also keep in mind half the 5 star reviews are bots.
