You are Gordon Freeman, or, as only a few people know, Roland Blackheart, a SAS officer with legendary skills. You were working for a foreign government, after you had been sacked from your original posting for disobeying orders. Your first job was going to the Black Mesa complex undercover as a research scientist. Your mission is to airdrop into the nearby area by Chiang research ltd. and infiltrate one of their secure supply passages. You will be accompanied by Mc Hamish here, and also one of our technical experts, to break into their security systems.
