Medical Notes
Thanks to the thoroughness of the Black Mesa medical personel, not much testing was required. Subject's HEV suit had a full copy of subject's entire medical history. What follows is a summary of a direct download from subject's HEV suit, serial number #DA352145:
"KNOWN HEALTH ISSUES PRIOR TO EMPLOYMENT AT BLACK MESA:
Subject has no known allergies.
Subject has had no major injuries prior to employment at Black Mesa.
Subject has had the following minor injuries, prior to employment at Black Mesa: one minor concussion, one eye (left) injury (corrected with surgery), one laceration (splitting the right eyebrow, and requiring five stitches), the usual array of scrapes, cuts, and bruises that are to be expected during childhood.
Subject has had the following surgeries, prior to employment at Black Mesa: tonsilectomy, appendectomy, one corrective eyesight surgery.
KNOWN HEALTH ISSUES SINCE BEGINNING EMPLOYMENT AT BLACK MESA:
Subject has suffered the following major injuries: one near-fatal acid burn, broken left radius (while making an unauthorized 'sight-seeing' visit to the zooilogical research wing).
Subject has suffered the following minor injuries: three cases of hazardous fume inhalation, one minor concussion, two cases of radiation poisoning.
Subject has had the following surgeries: one corrective eyesight surgery, two plastic surgeries (scar-removal), one experimental bone-graft.
BLACK MESA MEDICAL PERSONEL NOTES:
Thanks to a special 'volunteer clause' in the contract of every employee of Black Mesa, all applicable injuries suffered while in the employ of Black Mesa are to be treated with any and all available experimental treatments from the medical research wing. Thanks to this clause, all injuries have been successfully treated with no ill side effects currently apparent. Observation continues, so that we might spot any future side effects.
Also, despite two successive corrective eyesight surgeries, subject's eyesight has not been fully restored to 20/20 vision. Subject has been advised to continue wearing glasses and/or contact lenses."
Subject appears to have sustained numerous broken bones, lacerations, and other severe trauma. HEV suit also shows signs of severe wear and tear, with repairs mounting in the thousands of dollars. This is attributed to past run-ins with the US Marine Corps, various government assassins, and the Xen entities that invaded the Black Mesa science compound during what is being dubbed the "Xen Incident".
Distinguishments
Mac has had only a few notable battle accomplishments since his joining CWAL, thus little is known about his style of fighting. Those incidents which have been observed thus far seem to indicate a sporadic, almost random style, which seems to change from battle to battle with no known set criteria defining which weapons should be used in what way. He has been known to attempt sniper tactics in a melee battle, but also charge boldy (and stupidly) ahead in a ranged combat. While the weapons he uses vary from battle to battle almost as randomly (and inappropriately) as his style, he seems to favor explosives and high-calibre, automatic projectile weapons. This, despite the unsubstantiated rumors that he has "obtained" certain Maggottonian energy weapons. While he admits nothing of this, it is believed that he has not yet managed to aquire anything equalling or bettering a Cratermaster in power output levels.
When not engauging in or preparing for battle, Mac typically spends much time on the CWAL computers (as CWALers invariably do). Mac seems to like to have his ego stroked by playing Half-Life, the game modelled after his adventures at the Black Mesa Research Laboratory. Mac seems to have an affinity towards pizza, as well as any meal involving meat and potatoes in large quantities, and beer (all of this supporting his claims that he is 100% Irish American).
History
Mac's early years and education are not out of the ordinary. He attended grade school, middle school, and high school as any other human youth would. His college career was also analogous to most human youths, although he managed to get a Ph.D. in an otherwise very difficult field, that of theoretical physics. It may be worth the minor notes that Mac has taken several years of Latin as a foreign language (uncommon, possibly useful, but not exemplary), and that he did his thesis work on the effects of energy on time on the quantum level, as mass is energy, and mass affects spacetime.
During the time period between his graduation and the beginning of the "Xen Incident", Mac's records seem to taper off into oblivion. A few records have been indicated to exist, but are concealed by so many government security clearances that it is impractical to locate and investigate them. Mac has summarized this time period by stating that he was "sponsored" for a job at the Black Mesa facility by an unknown, apparently high-ranking individual. Mac was trained and put to work, where he performed several classified experiments up until the day the gateway to Xen was openned.
Following the openning of the Xen gateway, and for the next several days, Mac's records pick up in an almost unparalleled level of detail, as the VALVe Software game Half-Life covers the events in near-perfect historical accuracy. After defeating the Xen entity known as the Nihilanth, Mac was contracted by VALVe Software to perform two tasks: sell his tale of survival to be made into a game, and work as an assassin-cum-demolitionman to eliminate a major competitor of VALVe. During his first and final raid on Blizzard while working for VALVe, Mac was captured. After escaping, he made his way to CWAL (not a difficult feat, as CWAL HQ is directly across the street from Blizzard HQ) and joined the group in hopes that he could complete his contractual mission assigned by VALVe and have fun while doing it.
