Paragon options are generally the good guy, heroic actions that make others love you.

Renegade options are the harsh, bad-a actions that make others fear you (or in the Krogan's case, respect you)

Mass Relays are like teleporting machines out and about in space that ships use to charge their FTL (faster than light) engines to go to and from galaxies, making space travel possible. These were left in space over millenia by the Protheans (although likely further) and were the Reaper's tools to develop civilization for their own messed up purposes.

The Omega 4 Relay is the mysterious mass relay out in the Omega cluster that is a direct line to the Collector base. You'll spend the majority of your time in Mass Effect 2 preparing to go through it.

Star Maps are found on Illium in the lower shops, to the right and in the back (next to police area).

I reccomend choosing to be Paragon or Renegade mained early on so you can make those special cconversation options that allow you to do things you normally can't. For example, some of your crew will get in a fight over time, and you'll need a high enough score of either to move on.

I also reccomend NOT choosing soldier as your class, you will get really bored. I personally went for Infiltrator, but any other class is good.

Hope this helps.

Paragon/Renegade : During dialogue, if given an option, choosing one of these options will give you paragon/renegade points. Usually upper right options is paragon,lower right is renegade. The consequence of paragon/renegade is usually story lines. Getting higher points on one side grants you persuasion/intimidation option that you can use in your dialogue. This will also affects the story line.

Mass Relays: A gateway for you to travel between nebulas/galaxy. Usually way to travel during normal missions.

Omega 4 Relays: A gateway to your final mission. Not accessible in the beginning of game

Star Maps: Go to Illium on the side where you can buy weapons. The star maps are on the right balcony toward the end.

to put it simply be an @$$ hole if you think that dong something is mean or unkind or downright ruthless do it and laugh at the children that shepard just spat in there eyes will get that renegade in no time
