Hi. Unreal had a red cross as a symbol for health.
As could you see here
However, in Overwatch, the red cross is changed a little
Also, in some Transformers products
So the question is- Is it possible to use a red cross in your game, styled in such a way that you won’t get sued ? The idea is that the player should know instantly what that symbol represents. What could be the minimum ammount of modification required in order for you to be on the safe side ?
