Resistance Co-op Questions?

May be...

I've had my PS3 for a while now and some how never got into the Resistance series, so I decided to buy both of them. So while i'm waiting for Amazon to ship them I have had a few questions come to mind.



1. Does Resistance Fall of Man's offline co-op allow a player to join or drop out at anytime or does it have to be a set co-op for the entire thing.



2. Does it have online co-op?



3. Does Resistance 2 have campaign co-op offline and online?



4. How many people still play Fall of Man online?

1. it is either single player or co op for entire thing



2. no online co op for single player campaign in either oen just local



3. Single Player campaign can be offline but not online but it has a 2nd campaign made for online play only with 8 players



4. Not too many but enough people play it where you can have an experience but most play Resistance 2
