There's a reason why you rarely see the Red Cross logo in modern games. This is why it's extremely illegal for developers to include it.
If you want to be really triggered, look up the most outrageous game ever created. Because despite all of the nasty stuff you'll find in that game, you won't find the Red Cross logo, and so there's nothing in it that can get it banned. Yes, you can put some nasty s*** in games, but if you include the Red Cross logo, it's illegal.
Why Is The Red Cross In Video Games Forbidden?
The Red Cross logo isn't a universal symbol that anyone may copy for free into their products; it's a protected symbol, which is prohibited by the Geneva Convention for its use without permission. This was intended so that people would know to trust the symbol even in times of conflict and strife.
Let's continue the discussion about what you shouldn't see in gaming...
What Is The Penalty For Using The Red Cross In A Video Game?
There has been only one recent instance of developers being penalised for including a Red Cross logo in their game, Prison Architect, and in that case, they were given a warning before any further action was taken. They were informed by the International Committee of the Red Cross that this is:
The developers removed the logo, and everyone moved on. However, it was still somewhat unfair that these developers were targeted, given how many other games still use a red cross on a white background to represent health packs and such. They were probably targeted because Prison Architect is a serious game in itself, and not something a charity would want to be associated with.
The red cross isn't a universal symbol, it's just a reference to the Red Cross charity in games. This is why game designers may not simply use it in games that need medical attention. Most games, like Halo, have quietly replaced the cross with a white H.
