The new matches feature is going to allow you to create games with very specific rulesets, so that you and your opponent(s) can have a good ol’ fashioned throwdown without say, mortars, getting between you and ripping your opponent apart with a hail of bullets.
You can also specify a time and place to duel with a single enemy, as well as other ground rules that make sure that the two of you have a good scrap. If you need to bring more people into the bout, then all the better.
There’s a lot of depth to the system, but there’s also a downside; You can only use this feature if you’re actively renting a dedicated server. You need to organise everything yourself on your own server.
