Swedish Officer Training
A rather cool multiplayer game where each person has a quarter of the screen and a health bar that slowly ticks down. As you complete tasks, health is restored to one of the players next door and the player on the other side restores your health for completing their tasks. So you have to have the next player's back while you have to trust someone else has yours or you all die.
The Swedish Armed Forces ? The team test

played this with friends many moons ago, its very addictive and good fun over voice comms.
