The '''submarine''' is a submersible cut from ''Half-Life 2''.''Half-Life 2 Raising the Bar''WC mappackHalf-Life 2 leak|''Half-Life 2'' leak fileshttp// ''Marc Laidlaw Vault'' on the Forums

At the end of the original ''Borealis (cut ship)|Borealis'' chapter, Odell and Gordon Freeman were to leave the ship with a submarine, and set off to Kraken Base.

While no submarine is present in any of the ''Borealis'' maps, ''Raising the Bar'' indicates Kraken Base to be the next location, and the most complete Kraken Base map, proto_deep002b.vmf or  proto_deep002, indeed features a small submarine http// brush located in the only possible entrance (other than teleportation) to the base. Moreover, Odell mentions getting to the submarine in his dialogue files, and the journey was confirmed by writer Marc Laidlaw.


The WC mappack map props_borealis shows that at least 4 models related to the submarine, but not found in the leak, were present sub_thrusters01.mdl, sub_rearcone01.mdl, sub_oxygentanks01.mdl, sub_canopy01.mdl.
