About IRON VAULT: Mecha Arena
IRON VAULT is an original 2v2 team mech action game. Lock on, shoot, dash and slash - fight beside your wingman and break the enemy team before your Team Cost runs out. NEW IN 1.3: online co-op boss raids for 2 to 4 pilots against giant bosses. Empty seats are filled by CPU, and Quick Raid starts at once. ONLINE BATTLES (NEW IN 1.1, OPTIONAL) - Online 2v2: create a room with a 6-character code or invite online players; choose who to invite, and CPU fills any empty seats - Quick Match: Casual or Ranked. Casual fills empty seats with CPU after about 30 seconds; Ranked needs four real players - If you disconnect, a CPU takes over your mech and you can rejoin within 20 seconds - Every match gets a combat score; ranked rating climbs through 18 military ranks, with ACE for the top 100 players - 8-week seasons with global, season and weekly leaderboards; pilot cards show wins, losses and play time, and you can add friends - Optional: Game Center sign-in keeps your online record across devices; invite and match-found notifications can be turned off - No ads in online matches TWO FACTIONS, TWO STORIES - Play the United Control Authority (UCA) or the Free Ring League (FRL): 31 chapters and 52 stages in all - Wipe-out, survival, target-destruction, escort and giant-boss missions - Clearing chapters unlocks new mechs as both sides head for the final battle 7 GIANT BOSSES A six-legged siege walker, a transforming flying fortress, an aerial battleship, a super-heavy tank and more. Target their weak points and bring them down. 17 ORIGINAL MECHS All-rounders, artillery frames, transforming interceptors, a remote-weapon commander, a sword-and-shield duelist... every mech has its own shooting, melee and special moves. 21 BATTLEFIELDS Colony streets, an asteroid base, orbital debris fields, a rainforest naval base, snowy ridges, red deserts and giant fortresses - on the ground and in space.
