To avoid having to kill all the enemies in the Liberator yard, use a replay just after you enter the yard (as the enemies are moving to their positions) to stop them from attacking you.

Video probably explains it better:

I drove over the wrong guy at the start, so I got shot a bit at the end, that guy is the only one that becomes hostile though so driving over him means not getting attacked at all.

Also get hype for garage rng, lol.

Amazing strat, Lighnat0r! Can't wait until I'm done with VC and eventually go back to 3! ;D
