Left 4 Dead
This achievement should come naturally while playing however it is possible to grind it while playing solo.
Start the first mission of any normal or above difficulty campaign, shoot a team member until they become incapacitated and help them get up.
Do this twice and then allow the AI to heal. Continue until you have run out of health packs and then kill your teammates. When you're the final character left run forward and let the infected kill you.
Repeat until the achievement pops (you can gain 14 revives per cycle).
