[Update]: Total War: Troy's second faction DLC is bringing in Ajax & Diomedes.
While they may have taken quite a few months to get here, Total War: Troy's multiplayer modes have now finally arrived as a part of the newest beta test. Much like the rest of the Total War series, Troy's multiplayer will allow you to engage your fellow players in isolated and PvP-focused battles, as well as on the campaign map where you'll be able to either cooperate or work against each other.
Multiplayer battles will be able to host up to eight players (in any combination from 1v1 up to 4v4), while the campaign will only support two. Each player will be able to use all of the playable factions from the campaign, along with their unique unit roster and various mythical creatures, which should give the whole multiplayer experience a nice bit of depth.
The good news doesn't end there, however, as Creative Assembly has announced there will be even more to come in the next few months. What exactly that 'more' might entail, nobody currently knows, but considering that Total War Saga games are a testing ground for new mechanics and features, I wouldn't be surprised if we get something wildly unique and experimental. Who knows, it might even be a new multiplayer mode!
Speculation aside, you can learn more about the upcoming Patch 1.4.0, as well as join the beta yourself, by hopping over to the official website. Have fun, and once the next major update goes live I'll make sure to let you know as I'm quite curious myself!
