coop is a different story then single player?

[One death guy]

hey guys, I have a question story-wise

I just finished Portal 1 and was really hyped about starting this one

before I go into single player campaign I wanted to play with a friend the coop

should I finish SP campaign before I start playing coop? Or it wont matter for the SP story if I play coop first?

hello,

coop-campaign is a different story than a singleplayer mode - totally different characters, puzzles and setting, so if you start coop-campaign first you don't ruin anything and will enjoy singleplayer later. there are might be the minor spoilers/lore here and there, but overly the events of singleplayer and not connected with coop-campaign

I would however recommend to finish singleplayer first, because singleplayer introduces lots of new mechanics, that Portal 1 didn't have. so starting coop-campaign without clearing singleplayer first might pose to be a bit tricky to grasp new gameplay gimmicks here and there. but, anyway, as you wish - I suppose there is a great charm of figuring out stuff with a friend together =)

thank you that was vrey helpful. The new mechanic thing helped me make a decision, I will finish SP first before jumping into coop

Hi !
rarestMeow said it all...
However, if you need a mate for the coop i'll be glad to do it with you.
I need "Professor Portal" achievement. Plus, that's always a pleasure to play at this game but I need a mate too
