@ scvs.. that is something that affects balance, and thus super-cedes the rules of logic
@ healing lings: it is and they do... fast
infact if you were to calculate their rate of regeneration, it would likely be quick enough to watch the wounds close up before your eyes.. and heal over a 10~ 15 minute process (real time), (or roughly a 30 second process gametime)
@magically produced: again a balance mechanic.. but who knows maybe their clones
and are magically produced, just in an under-exagerated time..
@wounds healing over a life time... depends on the types...
because marines are in an armored, suit, i would asume 80% of injurys are bruises/concussions ect... which do infact heal rather fast (a week or 2)
im not sure, but the game has a day/night cycle? atleast in some campaigns...
which is roughly 8 minutes per cycle, which seems like a reasonable under-exageration of the actual day, making the whole setup more believable..
Nowdays fully healing over a 2-3 month period, for
some near-fatal injurys isnt all that unbelievable (55(marineHP) = 27 'day/night cycles' roughly 1 month) especially since im sure, that marines in that era, have quite a few medical advances, they can apply to themselfs (nano-bots?), stim packs.. ect...
@zergling getting 1 attack on a marine would kill him
well i asume you asume this wound would get through his suit, and hit a vital body-part...
either way, without feelings of 'pain' which medication can easily bring..
the marine wouldnt keel over.. and steroids would keep the heart pumping... aswell as whatever other advanced triag the suit itself has equiped inside....
@ the attack system
i believe it is already built around chance... but without the chance (average)
they figure that a zergling gets an attack in... it may 'kill' its target..
but not every hit actually would hit its target, (im sure marines can dodge claws sometimes), so rather the game asumes, the average marine can dodge an average 10 attacks in his life-time...
so then they just make it easy for the users.. and say.. after 10 attacks the unit dies...
otherwise every attack would deal 0-(a rough estimate of max dmg, likely the strongest attack in the 99th % of chance (an attack even from the weakest unit that can even harm someone, would have the potential for a perfect critical shot) (people have died from paper cuts, although its a slow death from disease... its root cause is still a papercut)
