Outpost 1, doubtful. This is Sierra we're talking about... They're alive in name only.
Outpost 2, as I recall, was stored on tape drives that were left in a storage locker. After failure to pay the lease, they were destroyed.
So yeah... that's the legacy of Outpost 2. Developed, published and ultimately forgotten about by the original IP holders. Only way to get the source code now is to start fresh.
