Accessibility in games is more important now than ever, thanks to changing legislation in the US and increased awareness among consumers. Major game companies are trying harder to make sure everyone can play. EA’s surprise Titanfall battle royale Apex Legends provides a good example for how you can use clever in-game communication features to make life easier for players with speech or language disorders.

Apex Legends’ “ping” system is a method of communicating that doesn’t require speech, perfect hearing, or typing, meaning it’s accessible to a far greater variety of players besides the usual glut of people shouting commands to each other over headset mics. It allows you to use specific button prompts to paint targets, communicating detailed commands to your teammates on the fly.
