Mass Effect: Prima's Official Strategy Guide is very helpful for those finding the gameplay difficult to progress!

I recently bought Mass Effect: Official Strategy guide https://www.primagames.com/games/mass-effect/products/mass-effect-pc-eguide

I was stuck on quite a few parts in the game which were difficult to progress even with countless of walkthrough guides found on the internet.

But this guide was particularly helpful as it covers all of the guides, tactics, strategies, etc in comprehensive detail. I spent around 5$ for it from the official Prima website. But you can buy the same book for slightly cheaper than that at around 3$ from ebay.

If anyone is stuck with any gameplay/progress, I highly recommend Mass Effect: Prima's Official Strategy Guide.

There's plenty of free guides and advice online though. No need to buy a strategy guide.

masseffect.wikia.com is a better source of information. There is a walkthrough for every game. And it's free.
