Insurgency‘s latest game update, which also happens to be its biggest one yet, it now available for free on Steam.

As you might have gathered from New World Interactive’s gameplay presentation earlier this week, the new update, dubbed “Nightfall”, adds brand new gameplay elements by introducing night variants of pre-existing maps, including a day and night variant of a new map, Verticality.

The new theme puts emphasis on gadgets like the night-vision goggles and flare guns and creates challenging new experiences in the new cooperative Survival game mode.

According to NWI Founder and Game Director Jeremy Blum, “Night warfare is intense and sometimes scary in Insurgency. The Survival game mode has proven to be a great addition to the game, catering to players interested in a compelling cooperative experience that focuses on scavenging and evasion rather than progressing linearly through a map.”

A new party system lets players form a lobby and join multiplayer matches as a group. The feature is still in its early stages, however, so expect new updates down the road, including competitive matchmaking.

Lastly, many weapons have be overhauled with new sounds and animations while two new weapons, the AK-74 and M4A1, have also made the cut.

The studio has supplied a full list of patch notes so you know exactly what’s new in Insurgency’s free Nightfall update. Have a look below:

  • Add command line arguments as alternative to cvars: -workshop (enables workshop), -nowsmapcycle (disable starting a mapcycle), -wsrandom (generate mapcycle in random order).
