HeadfulofSandvichIs that actually an fps moba? all I ever remember hearing about that game was that it was some shitty pay-to-win fps made by the same guys who made HoN? Correct me if I'm wrong, I have no actual idea.
Essentially, there are two teams, each has 16 players. One of those players plays as the "commander", with an RTS perspective of the entire battlefield, complete with fog of war. He can build outposts and expand his base, along with providing buffs to players. His role is to literally command the other players, guiding them with his unique perspective of the battlefield.
The other 15 players on each team play in a first or third person perspective, running around across multiple lanes (map design somewhat reminiscent of Dawn of War 1), capturing bases and killing the other team. Each time you die, you can respawn as a different class. Classes have roles, rather than direct counters like TF2 - there's essentially support, ranged, and melee. By killing other players and by capturing outposts, you can gain money which you can spend on consumables or on playing a life as one of the tier 2 classes, which are stronger versions of the free tier 1 ones, essentially. You can also from time to time play as one of the giant siege units when granted by the commander, for assaulting the enemy base. Players are divided into squads with squad leaders, sort of like Planetside, and the commander can issue orders per-squad.
It essentially boils down to a class-based FPS AoS-style game for 15 players per team, while the last player plays from an RTS perspective.
It went free to play long ago. It isn't really pay to win as far as I remember. It ran on fucking everything, it even had a wonderfully performing native Linux client. It's a shame it died off, it was honestly a wonderful game and if a Savage 3 were to come out today, it would do wonderfully.
