Mod DB | MediaFire | The Nexus


Set in the 22nd century, Mass Effect, developed by BioWare Corporation, is a third-person, role-playing shooter that focuses on the story of Commander Shepard, an Alliance Marine who must do everything possible to save the galaxy from the Reaper threat.

Mass Effect: Unification is a total-conversion mod that adds the Mass Effect era to Instant Action. As of v1.2 (R5), you can fight as the Systems Alliance, the Heretic Geth, the Collectors, or the Evolved Geth on three new custom maps, most of the stock maps, and all maps from the Sol Map Pack.

0 comments by Marth8880 on Jun 28th, 2015


Yep! That's right! Seeing as how it's Summer and I'm on break, I figured I'd publicy release what I've worked on during my past few seasonal two-week breaks. Among various other updates - such as improved rifle and pistol animations, and new CTF mechanics - you can finally test out the brand new custom HUD that I designed as well as Endor, which is finally supported! (special thanks to AQT for revamping the map) Not only that, but you can download and test them out right now in the open beta! I'm releasing another open beta because I need feedback, and seeing as how I got a decent amount of it from the previous open betas, I've decided to let you all give things a shot and help debug the mod! (A third time!)

Want a complete list of the changes and additions that are included thus far in this patch? Follow the second link below!

View R6 Change Log


To install the patch, view or download the build manifest by following the first link above; the build manifest contains everything you need to know about this build. As soon as you have the build manifest open, next to "File Path," follow the link "Patch Version (R5-R6) (Mediafire)" to download the R6 production patch setup file.

If you do decide to play the open beta, I implore you to not just pass up any bugs you encounter as things that "somebody else reported/will probably report," but instead take the 5-10 minutes to report the bugs. It's easy, it doesn't take very much time, and it will help improve the mod. Don't feel obligated to report things, but keep in mind the simple fact that the quality of the mod is largely based on the bugs that are and are not reported.

Hmm, interesting. What are all of the steps that you took to install the mod, and do you have the unofficial 1.3 patch installed?

I had downloaded the mod to my computer then read the instructions I put all the files into the game in an Addon folder. Then I looked up my screen res. Then I clicked on the AspectRatiomointer_16-9. bat to download it like it said in the instructions And the commands prompt only came up for less than a second then disappeared. And Im using windows 7 . I had thought that was it and the mod worked. I got onto battlefront 2 everything worked until i got into the game itself I went into Instant action started a battle I can see the geth and alliance solders but when I click on them to play as nothing happens. It's stays at the classs menu and I can't play. Any options?

I have to ask, might Batarian Terrorists/Slavers be a faction at some point? I think it would be cool to see them in their blade armor spam Kishok harpoons across the map at Alliance troops.

Your mod had an Epic Foreshadowing with the Geth Prime:
Now we can play as one (But smaller) in ME3 and it even shares some attributes, like being a slow unit with an absurd amount of health and firepower.

I tried out this mod, and I gotta say the look and feel you have down. I was visually blown away by the player and weapon models, especially the Geth. I have encountered one annoyance however: The use of shields on players was pretty cool, but at times and with certain classes/weapons it's almost impossible to land a killing blow on the simplest of enemies. I use about 3-5 clips while using the Tempest to take someone down, and 4-6 shots to kill with a viper. My suggestion is to either increase the damage dealt by the weapons/abilities, or to re-work the shields/health system to make a tad less annoying in a firefight. I also agree with a previous poster about streamlining the abilities and weapons on the alliance classes. Other than that amazing work! Keep at it!

Re-reading this I feel really childish. I gotten used to the new gameplay style (The health bars really change a lot) I fell in love with this mod! I don't know what I did, but the gameplay improved a ton after a little while. The mod still needs some streamlining, and I've encountered a bug where collectors are the only people who use heroes(and when I switch off heroes Harbinger still haunts me) and other than that I have had so much fun with this. Here me out on this other players: Play Felucia as Alliance, with max number of players. It is ridiculously fun! One of the best mods for any game I've played!

Preferences are preferences, it's actually pretty simple, go into the "C:\Program Files (x86)\LucasArts\Star Wars Battlefront II\GameData\addon" folder and delete the "ME5" folder, that should get rid of all the UI changes, maps, etc.

Doesn't change the main menu music back, though... Wouldn't mind knowing how to fix that whenever I just want to completely "switch it off" once in awhile...
