A few months ago I found out about this game called Surviv.io.
It's an amazing game.
the game is a 2D overhead view battle royale with 80 players per game. Players don't drop from a plane, they just spawn at a random location. The map is completely random too.
There are so many guns. From the weak M9 to the amazing AWM-S, this game has the guns for every play style. There's also melee weapons.
I could talk about this game all day. I encourage you to check it out.
