In single-player, EMT is a one of Trauma Team
's harder modes, and only gets harder in co-op. Rather than perform tasks on the same patient, each player is charged with a different patient in the workload. In single-player, you can quickly switch between patients, but in co-op, you need to wrap up your patient as quickly as possible before your fellow EMT can move on to theirs. As you'd expect, this leads to a lot "encouragement" between players; you're not just racing against you're patient's clock, but your partner's as well.
