Webb's Guide To The Galaxy


Recommended Posts

The galaxy in Mass Effect is absolutely huge, so here is a comprehensive guide to all the planets that aren’t part of the main missions. Firstly, this isn’t everything, but it is most things. The places you encounter across the galaxy have a really rugged terrain on the whole, whether it be the Martian like landscapes, the scenic utopias with several suns or the snow ridden wastelands, they all have different attributes, but are as equally as amazing. My personal favourite – Maji in the Vamshi area of the Armstrong cluster, two moons and a red Mars-esque landscape! Quality!


Secondly, let me give you some pointers for the unchartered territories and the controlling of the Mako. The Mako is an incredibly versatile off road vehicle but it’s not invincible. It can pretty much climb most terrains, but if the decline is too steep it won’t climb it. There is always a route in to the key areas, like debris, anomalies, etc, so if you are struggling the one way, check the map and the contours and try another route. Zig zagging across steep terrain is sometimes an option. The vehicle has a boost which is the A button, however, use this more to break falls than to climb stuff as it can kill momentum and the rules of physics say, if you boost off an incline, you will only go one way, up and then down. Use the way marker ability on your map to navigate around the huge planet surfaces. Stock up on Omni gel which you can use to repair your vehicle, if you plan to do some off-roading as the Thresher Maw’s can always appear and give you a beating and there are plenty of other worries such as pirates, Geth and many more to attack you. That should be enough to get you going. Now, below is a comprehensive guide of what you can find on every planet (work in progress remember) in the galaxy. Any planet not mentioned will have nothing to do on it, or with it. Remember, these are only planets of interest that AREN’T in the storyline.

Armstrong Nebula - Tereshkova - Antibarr


Note that there is a minerial south east of the prothean ruin.


Any idea what? No biggie if not, I can whizz by there tomorrow and check it out.


on Edolus in the Sparta system, the lithium is actually marked on your map


Are you sure? It wasn't on mine, well, not until I surveyed it. I always check the map first and write down what I have to check and add any extras in later.

when do you receive the mission from the consort about the elcor? i have completed a mission for the consort but i dont remember any elcors involved.


It was just after you talked to the dude in Chora's Den and stopped him from spreading shit about her. Then he gives you a job after.

As much as I hate GameSpot, I did find this...




I didn't realise I still had a whole system to unlock (Styx Theta) plus a few new star clusters in the Hades Gamma sector, certainly saved me trawling all the planets for the millionth time.


Hope this helps and thanks for the guide DaWebbmeister!
