Bad Company 2's Conquest and Rush in Arma 3: BC2's kits, M-COMs, points, ranks and real sounds and voices vs an AI army with jets.
Battlefield: Bad Company 2 in Arma 3. Conquest and Rush on Altis, Malden or Stratis: your squad (solo or up to 8 friends) fights next to an allied AI army against an enemy AI army — NATO against CSAT, or any armies the host picks — both with tanks, APCs, attack helicopters and jets that come back at their bases after they're lost. Bigger island, bigger battle.
Pick the armies. In the lobby the host picks each side's army: NATO against CSAT as in BC2, or any faction of Arma 3 and its DLC — AAF, FIA, Syndikat, NATO / CSAT Pacific, LDF, Spetsnaz and more. Soldiers, crews, tanks, APCs, AA, helicopters, jets, artillery and your four kits all come from the faction you pick; a faction without tanks or jets fights with what it has. Any faction can fight on either side.
From your own Battlefield: Bad Company 2, if you have it (optional: read from your install on the first Play; BC2 is never started or changed — without it you play the same battles with Arma's own sounds and voices):
BC2's rules:
One player presses Play and hosts; the host picks Conquest or Rush, the island, the battle size and the armies, and starts the round. The lobby has an invite code (COPY INVITE CODE); friends copy it (or the host's address from this page) and press Play: the launcher asks whether to join that game. Up to 8 players, through Steam's relay — no port forwarding.
Arma 3 (base game; Malden is the free DLC that comes with it) and Steam (the mod starts it for you if it is closed). No Arma DLC is needed (the DLC factions are there for those who own them). Battlefield: Bad Company 2 (Steam or EA) is optional: with it the first Play reads its sounds, voices, music and art (about a minute, ~150 MB in your local app data).
The same game without the launcher and BC2 is also on the Steam Workshop: https://steamcommunity.com/sharedfiles/filedetails/?id=3819118287 — there it also takes factions from your other mods (RHS, CUP, ...).
