I tried Hunt Down the Freeman. It gave me a mission in a wasteland to take down Combine commander. I got pistol, crowbar and medkit along with energy bar. First enemy is Combine Overwatch with 24 HP, jetpack and rocket launcher doing 8 damage per shot. Both pistol and crowbar doing 1 damage to him. I forgot to heal and just started smashing him with crowbar repeatedly. He outgunned me and i died. 10/10 would Freeman again. But seriously, you can do so many wacky things with it. I don't know why this don't have more attention.
