Even L4D will get boring if we just play it trough again and again, but if we make some new ways to play it then it can work in even longer time so I have figured some fun ways to play.
All the ways to play makes a little competition, but Teamwork is needed so it is about how much you can trust your friends
Bounty Hunt: Kill most Special Infected, simple...
Hunt: Kill most Infected, Simple again...
Survive: (High difficulty for most fun) Play and survive for as long as possible (Enemies will keep spawning)
And now my Favorite!
LEFT 4 DEAD RACING: Get to the saveroom as fast as possible, but with a difficulty like Expert you need your friends at all time to survive and it really is hard!
The diffirent Acts in the campaign are like Diffirent Races.
