For infinite Acid Spit
:
First go to tank containg the Reaper and 3 head crabs and fire
at second control panel to left with the 'Shock gauntlets' a
scientist with a pink tie will shout "What is that thing doing
it might have shorted out the whole system,get that thing back
in its cage immeidiatly!" 2 scientist will then drag you back
to your cage but you should slash to stop them, now follow the
signs to the morgue, you are there you will see a scientist
being attacked by a reaper and a security guard trying to shoot
the 3 head crabs don't interveine as the security guard will
miss all the head crabs and shoot control panel (stand well
away as it will expode killing the security guard and the
head crabs) then you will notice a morgue draw slightly open
slash it and a disected alien will fall out feed off of it and
this will give you full health and acid armour and
infinite acid spit.
