Survived 10 explosions in multiplayer.
While playing, there will be times explosions happen. This can be from launched grenades, mines, etc. The explosion must damage you, but not kill you. There are red barrels around that can be shot, but it maybe impossible to survive those.

Online private match boostable (by yourself will work)

You can go into your own match and shoot grenades on the ground (with the right loadout). Be careful, as being too close will cause you to die.
