Dead Space: Extraction staying away from strict co-op rules
This information comes from Nintendo Power…
“We know a lot of people out there like playing with their friends, with their family, and so we wanted to support that. But the other reason [for the co-op play] is that we kind of wanted to move away from strict survival-horror rules – which are, you’re alone, you have to really watch your back, [and] conserve ammo all the time – and move more in the direction of action-horror.” – John Calhoun, senior designer of Dead Space: Extraction
As Nintendo Power notes, players will still need to be aware of ammo supplies, as gamers will use ammo from one pool.
