Playing games will be more of fun when played in group together with friends or colleagues. The games will be felt more alive with a party standing on one side and the other playing as the opponent. Recently, there are some tools or methods which enable games players to play their games in split windows. Unfortunately, some user found split windows / 2 windows cannot be used in certain games. An example of game which failed in doing this was Borderland. Though a complete tutorial was available on here Borderlands Split Screen pc (Tutorial), still the instructions were difficult to follow. There seemed to have been a problem in the controls. The buttons were not doing what they were supposed to do.
In many cases, such a kind of problem can be fixed by the use of Steam in offline mod. People can run as many steam accounts as possible. Anyone who wants to start steam in offline mode can do it by going to settings. Even if the internet is down, steam can still be opened in offline mode. The process may be a little hazy, but, the result makes it worth a try.
