Arma 3's major Apex expansion kicks off today, so here's a launch trailer

The long-awaited Apex expansion for Arma 3 rolls out today, following its announcement at E3 last month.

last month. Apex grows pretty much every aspect of the game, with the addition of a huge, South Pacific-themed 100 km² map called Tanoa, and a campaign supporting up to four players in cooperative play.

The campaign puts players in the role of a NATO CTRG special operator, sent to Tanoa on a humanitarian mission. Naturally enough, things go a bit pear-shaped and firearms come into the equation. These will be plentiful, too: Apex introduces 13 new weapons, in addition to ten new vehicles.

Most interesting is the island itself, which features a range of environments yet to be seen in an Arma game. According to Bohemia it is "home to lush tropical vegetation, unique landmarks, a rich history, and imposing man-made features of modern engineering". Landmarks you'll encounter include a sugar cane factory, shanty towns, an industrial port and, most excitingly, a bloody volcano .

Anyway, there's a launch trailer which demonstrates all these things in flashy visual language, and you can see that below:
