The game itself content wise is:
Cartoon style graphics.
Use of guns, grenades and other weapons.
No excessive blood and gore.
Once you are "dead" you simply vanish and enter a spectator mode.
It's battle royale so basically fight to the death, last man standing wins.
The main issues with it are:
Rounds are anywhere from 2 minutes to 20 minutes but the game cannot be paused.
Highly addictive, many wanting to "just get further next time".
The public voice chat, like with many online games, is unrestricted and often toxic/sweary and inappropriate for younger players.
It is often incredibly frustrating to play, causing players to get angry at the game.
It's free to play but there are loads of extras you can buy with real life money or you have to spend hours and hours playing to unlock some of them. These include cosmetic items such a outfits, dance or emotes as well as weapons.
Advantages compared to other first person shooters:
Graphics are not realistic.
No portrayal of actual wars like in games such as call of duty.
No overly complex storyline or plot to follow and understand.
No gore or drawn out deaths.
Free to play the basic game.
Rated 12, rather than 18.
