Battlefield V takes you back to the most devastating war in history; World War II. This iteration of Battlefield will be largely familiar to anyone who has played any of the previous Battlefield games as little is changed from them, but that's no bad thing.
The achievements are very straightforward and few in number, albeit somewhat tricky for some of the online miscellaneous achievements and frustrating to beat the War Stories on Hardcore, but it is manageable to say the least. There are only six achievements for playing the three War Stories; one for beating each and one more each for beating all three difficulties (Medium, Hard & Hardcore).
Note: This game seems to have an issue recognising when you have completed a War Story and thus may not register having completed one of them, however, you can just go to each one and select 'Resume' and it will play the final cutscene again and register. So don't worry about having to do them multiple times.
Step 1: War Stories
First and foremost you're going to want to complete the three War Stories. You should do these on Hardcore from the beginning so you don't need to do multiple playthroughs of them. They aren't very long and can all be done in around 5-7 hours. You will die very easily though on Hardcore and if you're not entirely adept at FPS games then you may struggle to get through them. See the description for "Sins of the Fathers" below for tips on surviving Hardcore, and each War Stories specific achievement for a walkthrough, of sorts, on how I got through them.
There are collectibles but they ARE NOT required for any achievements so feel free to leave them. They grant you a unique melee weapon for the online for finding them all on each War Story, so unless you want those, ignore them.
Assuming you play these on Hardcore from the start you will unlock "Lovely", "Store fuglar fanga ingi flugor", "Ou La Mort", "Storyteller", "Veteran" & "Sins of the Fathers", thus concluding the single player portion of the game
Step 2: Multiplayer
After finishing the War Stories you'll then be spending the vast majority of the game playing multiplayer. This will be hard to put an estimate of time or difficulty on as it largely depends on your skill level and just plain luck. You can attempt to boost the miscellaneous achievements online if you choose. Use the Official XBA Boosting Session Information & Discussion thread to find people to help you.
I would suggest just playing the game as you would initially and not attempt specifically to go for any achievement until you get used to the game and the maps. You need to earn 500,000 points total, as well as 100,000 for each of the four classes so these will take you the majority of your time to complete.
When you are feeling confident you can attempt the few tricky miscellaneous achievements, notably "Death From Above" & "Fender Bender". These two require no small amount of luck and perhaps even some skill with the vehicles. See their respective descriptions below for tips on achieving them.
Besides those two tricky achievements, the rest of them are either very easy, such as "Grim Reaper" that has you kill 30 enemies total online, or will come with natural play such as "Globetrotter" which has you simply play a round of Conquest on each of the launch maps.
All told, an unusually short list for a Battlefield game. Some difficulty is present but to anyone competent at FPS games and especially Battlefield games this shouldn't prove too difficult a completion. I'd recommend just enjoying the online for what it is and not worry about the achievements as they mostly will unlock naturally, other than a few of the miscellaneous ones.
