[Guide] How to unlock achievements "without retrying" in your existing playthrough

now i have 980/1000 with 46 achievement but the remain 2 cannot unlock..i retry without no success..

It depends on how much I am involved in the story of the game, for the halo series for example I first made a normal playthrough and then I started a new game following some guides and tips to unlock easter egg and skulls achievments.

For hellblade instead, since I read that you cannot backtrack or play only some part of the game to find the collectibles, I preferred to directly start my first and only playthrough with a guide.

I use very often trueachivment aand I think it is perfect for achievment hunters!

As far as I know, you can't max chevo ME1 on less than 3 playthroughs.

Yup, the absolute minimum is three complete playthroughs. And you can only keep it down to three if you read an achievement guide before starting your first game, exploit a certain loophole, and deal with a lot of awkward annoyance.

Normally, you're looking at four playthroughs at least, and quite possibly five.

The achievements in Mass Effect are all quite easy to obtain; but it's a big undertaking to unlock them all.

Achievement guide

This is a missable achievement and you can only obtain it from the 2nd half of the game onward.

To unlock the Chicken suit you'll have to complete the following:

Quest: Chicken Chaser

Worth: 10 Guild Seals

Location: Brightwall

How to Complete: Locate the farmer and he'll give you the suit. Round up all nine chickens to complete the quest and the suit will be all yours.

When you become ruler of Albion you have around 10 judgments. The rulings section is quite large, so it may take you a few hours to complete. The best way to do this is as soon as you're told to go to the Throne Room to decide on your brother fate, go to
the Sanctuary and put on the Chicken suit. Go to the ruling and once it’s finished it'll unlock!

This is missable as if you do all these judgments without wearing the suit, that’s it! You'll have to play a 2nd playthrough as these Judgments won’t come back.

It changed gaming for me, that i try to get every achievement possible for me to unlock. I play games first without any guide. After completing them i try to get the missing ones without a guide if possible.
