Friendly Fire: Jerome Jones Interview - Orcs Must Die! 2
The best reason for co-op is when the game is simply better that way. If a game is a fun rollercoaster of entertainment and orc viscera, then why not share the slaughter with a friend? What would you stand to lose? Nothing, unless you don’t have a friend and then you wouldn’t read Friendly Fire anyway.
(Tip: Friendly Fire is a suitable replacement for friendship)
There are games where Player 2 would break the intended atmosphere. Bethesda’s Fallout 3 has an environment of desolation and isolation that would lose something if you were never really alone ... and there was someone watching when you when you drank out of that toilet.
Some titles scream for co-op. Everyone wanted Orcs Must Die! to be co-op, even the developers at Robot Entertainment. Like so many great features and movie scenes, co-op was intended for Orcs Must Die!, but was left on the cutting room floor. Release date is an unforgiving mistress.
(Tip: Friendly Fire is a very forgiving mistress.)
From the beginning, Robot Entertainment saw the obvious potential for co-op in their dynamic orc-confetti simulator. In Orcs Must Die!, as last of a mystic order of guardians, you must use an array of traps, weapons and magic to blend, burn, mince, electrocute, crush, smash, cleave, rend, decapitate, perforate, explode, and generally kill all orcs. Placing the player down in the field of a tower defence title gave the player a personal hand in the destruction, and a front row seat when making orc-chutney.
