People seem to really enjoy the multi-player component in Mass Effect 3. I wouldn’t know as I still have yet to play the game, but general consensus is that it’s great fun. Free DLC packs definitely help make things more fun and BioWare is continuing to spread the love with a new DLC pack hitting next week.

The pack is called Earth and, surprise, takes place on the big blueberry that we call home. As has been the case since the beginning, the story behind the multiplayer is still all about taking back key locations from the Reapers around the galaxy. Considering that an invasion of Earth played prominently in the ad campaign for the game, it only makes sense to have it show up in multi-player.

So what will Mass Effect 3: Earth contain? Players will be able to access three new weapons – Piranha assault shotgun, Acolyte pistol, and the Typhoon assault rifle. On top of that, seven new human N7 classes will become available – Destroyer Soldier, Paladin Sentinel, Demolisher Engineer, Slayer Vanguard, Shadow Infiltrator, and Fury Adept. Each class features new abilities and melee attacks for players to try out.

The three maps that players will fight for Earth on include Firebase Rio, Vancouver and London. They will be available to play as soon as the pack is downloaded. Everything else, including weapons and characters, will be unlocked through existing Reinforcement packs.

Mass Effect 3: Earth will be available worldwide on Xbox 360 and PC on July 17. It will launch on July 17 on PS3 in North America and July 18 in Europe. As always, the multiplayer packs are free so no reason not to at least try it out.
