Naturally, Mass Effect 2 is a large game, and there will be holes in our knowledge- feel free to leave a comment on the relevant section and we'll see if it can't be added. This will be your companion throughout the game, providing you with anything and everything you need to know, be it skill stats, sidequest help, decision consequences, achievements- we look to cover everything.
Hello and welcome to our Mass Effect 2 Megaguide.
