I think the first sentence of the article has an 'AND' where it should have an 'AN'.
"After months of development by Jon God with help from Zeph, Deadfall, and extensive modification of Quarantine ( Quarantine ) , is finally finished."
might be me but it makes (more) sense when it reads:
"After months of development by Jon God with help from Zeph, Deadfall, an extensive modification of Quarantine ( Quarantine ) , is finally finished."
and maybe a semi-colon instead of a comma after 'Deadfall'? or maybe a hyphen? ("...Deadfall - an extensive modification of Quarantine - is finally finished.") beats me, punctuation is not my game.
