[PC browser game] [~2017-2019] the game similar to shell shockers but with humans as characters

I liked that game very much but now I can't find it anywhere at all. It was an online browser shooter (I could play it in Chrome) for PC and came out in the same year as shell shockers or year after.

The characters were humans with big heads and separated floating body parts. Game modes were capture the flag, battle royale and team death match. I remember a ctf map with castle theme and dm map that looked like some kind of a night playground with a big fort in the corner of the map made of colored tiles.

If I remember it correctly the game had two main versions: one is basically bullet echo but with those characters I talked about and then after one of the updates it became a fps shooter.

The last thing to say is that there was an expensive weapon and it was literally two golden AK-47 (and I guess two golden Glocks were too)
