ARC Raiders Frozen Doors: How to Melt Ice [Full Guide]

To open frozen doors in ARC Raiders, players must destroy the dense icicle barriers blocking bunker entrances by applying thermal heat sources like incendiary grenades or detonating high-yield kinetic explosives directly against the frost-covered entryways during active raid extractions. According to verified reports from Game Rant, these environmental roadblocks guard underground supply rooms overflowing with high-tier tech, rare weapon crafting components, and pristine ammunition crates. Players venturing into sub-zero raid zones frequently encounter sealed vaults frozen shut by cryogenic anomalies. Standard melee strikes and conventional ballistic fire deal negligible damage against the thick ice sheets, forcing extraction squads to expend valuable tactical inventory. Raiders can clear the blockage by hurling thermite canisters, triggering fire mines, or detonating breaching charges at the door base. While thermal weaponry melts the ice rapidly without alerting distant patrols, heavy explosives blast the door open instantly at the expense of broadcasting an acoustic signature across the map. Much like high-stakes tactical rotations documented in recent coverage of the [PUBG Mobile PMWC 2026 Roster Lock & Patch Notes [Confirmed]](/news/pubg-mobile-pmwc-roster-update-2026), strategic inventory preparation dictates whether an extraction squad secures elite salvage or gets wiped at the threshold.
