Are the challenge missions possible?

[Dr. Death]

I know, i know. "That's the point". But are some of the challenge missions even possible? specially the train one where you are forced to use fergie? They seem not just hard but also impossible to complete with 3 stars.

I have beaten them all with 3 stars. So I'd say yes. You just need a coop partner for them.

Hi,
definitely possibles. Anyway, some require several tentatives. Also, some characters may raise the difficult level, for example Fergie.

Yeah, i also noticed late that the challenge special tasks are unrelated to the stars. I thought one would have to get both the tasks and the 3 stars at the same time to do a challenge perfectly. Being able to go gun-ho with the breacher not caring about the stars was a breeze.

♥♥♥♥ that zombie train mission though.

The single screen one? smoke grenades made that incredibly easy. With the hostages the explosive guys can still be alive after getting shot or after a sniper shot, and if the hostages are in the way you are ♥♥♥♥♥♥.

You don't actually have to use Fergie to get three stars that is a separate thing. You can complete it with Fergie to get the medal thing or whatever it is then go back and get 3 stars with assaulter.

The train one? Yes. Three star it? Difficult but certainly yes. I know people say, bring a coop partner but I play on mobile so what is coop. For me it worked basically like this: First run was assaulter since hehe two ♥♥♥♥♥♥♥ goes bang bang. Three stars. Then picked Fergie and just completed the level. Stars don't matter the second time, the game just takes the best attempt. It certainly IS possible to three star it with Fergie, trust me, I did get the 20 hostages with Fergie too. I don't know what load out you are using but I follow the general advice I figured out when playing Fergie:
Use the revolver. Just trust me on this one, i say the five seven is also a good gun, but the revolver is probably the best one. Aimed shot oneshots armored and tough opponents like the HMG guys. Smokes are a must bring. Seriously you need them. The revolvers damage and accuracy make it pretty good for long range combat and even close range without hurting hostages.
So here is how you do it: Memorize where the bombers are. They are your main problem on this. Most can be shot through the windows with aimed shot. If you have to get into direct line of sight, approach from behind. You can run through the ground floor of the Waggons and see their rotation. Then pick the opposite one. Smoke, aimed shot, throw smokes forward, then aimed shot again. If they do their dumb down but not out thing, make sure you stay behind smoke and throw smokes while getting closer to them. Ready some ammo bags just to be safe. That's how you clear the bombers. Everything else? Smokes and aimed shots. Also, clear the upper levels of the Waggons before the final one. You will need it. Ready medbags on there, two, maybe three or as many as you can get there. Then bait the zombies out. Just get close to the door and they will all come. Run back and go upstairs again. The stairs are your broken friend on this one. When the swarm is a little away, go down, empty your mag, immediately go back up. Avoid damage and the fat ones projectiles. If you do get damaged, that's what we have the medbags for. Rinse and repeat. Anything that isn't a sprinter or the fat ones should be fairly easy.

About the get all hostages three star thing: I don't exactly know how it works, sometimes it shows all, sometimes it doesn't, even though I saved all. maybe the one zombie hostage at the last Waggon counts, maybe not. Don't try to rush into the Waggon though, you'll die unless you are breacher and even then it's close. If you don't get three stars instantly just try it again. Eventually you will get them.
Caution, smokes and aimed shot is the recipe to success in this one. That and abusing doors aggro mechanics for that specific one.
For the other levels it mostly comes down to memorizing the enemy positions and trial and error. And for the ones where you need recon: Mp5sd. Trust me. It's the best of his guns. It's underwhelming yes but it has aimed shot which is a crutch for every bad operator. Use smokes for tricky spots such as the dropping ceilings for one level. And the last one: The very last one? breacher, rushing, something with slugs and pray the slugs don't accidentally team kill hostages. Otherwise rush through and smoke off critical spots. There's your success recipe.

If you want to cheat, play an easy operator like the off duty guy with the ak. It has no recoil so you can safely full auto rooms without hitting hostages ever. It's damage is good, it's ap power is devious as well so you can get three stars easily. Then once you three starred the level with one operator then you just finish it with any star rating with the challenge. Voila. Three star rating and completed challenge. Hope I could help
