This organization needs to add ‘community building’ to its short - mid-term objectives for Predator Hunting Grounds. There are several examples of how different games have done this you can find online. I suggest a very simple ‘ADD AS FRIEND’ or ‘GROUP UP WITH’ button as an option before and after matches. The cross-platform functionality seems to not be at its best right now so restricting this to people on the same platform would still be a viable option.
Sometimes really cool people are in matches. Having the option to run another match or team up with really cool players would definitely build the community.
