How to unlock the Wasteland Medic achievement in Killzone 2 - Definitive Guide
UNOBTAINABLE DUE TO SERVER SHUTDOWN
Use the Medic's primary ability to revive downed players five times in a match. Pay attention to your radar for the green + icons to find downed teammates and this trophy should come quite quickly. You will need to have reached the online rank of Master Sergeant to unlock the Medic Badge.
To make this trophy even easier, when setting up your custom match, enable friendly fire. This will allow you to shoot and down the bots on your team. You can then revive them for credit towards this trophy. Thanks to kargorath for this tip.
*NOTE* This trophy may be unlocked in an online game against bots, but not in Skirmish Mode. Here's a video detailing how to set up an unranked game with bots: https://youtu.be/MGj9LBJjs2U
