Hey, i've been trying to play the coop mode with my brother on a lan. We are able to join each others game and start the game, but whenever we play it seems as if both of our games are running very slow as if we are getting bad fps. The mouse seems to move slowly and the movement is delayed which makes it feel slow. We both are able to run this game perfectly well on solo. I've also tried playing coop on the online mode and the problem happens online too.

Any help is appreciated, Thanks

Try to play it in lower resolution. It was doing the same to me when i was playing in 1024x600. I play it in 800x600 and it goes perfectly.
Also check your connection speed. Maybe you have slow internet.

Hi Rykane,

Are you both playing in the same household on the same internet connection? If so, it may be worth contacting your router manufacturer (assuming your using one) to make sure that:

1) The router supports NAT

2) That you have the latest firmware for your router.
