I think that Sledgehammer Games are going all out with the final week of the Call Of Duty WW2 Resistance Event. The contracts so far have all been pretty doable for this first Call Of Duty WW2 event and I think that is the same with this final week.
Get 35 Kills In Any Mode: This one is very easy as you should be able to rack this amount of kills up in a day or two.
Get 35 Kills With A Pistol: Just have a day where you play only using your pistol and you will be amazed at how quick you pull this off.
Get 55 Kills In War: This could be a bit tricky depending on your play style. I tend to go for the objectives more than for kills in War Mode so I will have to spend a few games where I focus on taking the enemy down rather than going for the objectives.
Get 5 Headshots In Domination: I suck at headshots so if I do this…. It will be luck. For you skilled marksmen though, you will be able to breeze through this.
Get 30 Kills In The Resistance Division: I am going to try and do this while I do the first two and I think that is the best way to go about it.
