My highly sought after pros and cons for the Overlord DLC pack;
PROS
- Interesting story. Self contained from the overarching Mass Effect 2 plot, but nicely paced with a good sense of progression. Wraps up really nicely.
- Overworld with the Hammerhead is really nice looking and much more interesting than the original pack. Feels closer to Bring Down The Sky, or like an uncharted world from the original game.
- Hammerhead used partially in some of the missions, including as platforming. Doesnt really outstay its welcome and is good fun.
- Droids and Geth are your enemies, but are not overused. Each 'mission' involving them is a really nice length that doesnt outstay its welcome.
- Pretty good environment variety. Doesnt feel like its repeating the same environment for the whole package.
- New music is good.
CONS
- If I recall correctly BioWare said there would be more dialogue in Overlord. That is simply untrue. There's not a lot of dialogue at all.
- Everything still ends in a shoot-out.
- Hammerhead combat is rubbish, as it has been since it landed, due to the extremely weak shields and the lack of any observable hit feedback when being shot. Fighting two turrets essentially requires you to camp out of reach, such as behind a structure, and have your rockets home in.
- The optional mission on the overworld is pretty pointless, and only rewards you with an achievement. It would have been nice to get an upgrade, or even some codex information or story details. Instead its just a collect-a-thon that really doesnt serve any point other than a time sink.
- The 'moral choice' at the end is as paper thin and black and white as most of Mass Effect 2; you either do the obviously good thing, or the obviously evil thing.
Ultimately Overlord is more of the same, both for better and worse. On the plus side, it retains the great combat and feel of Mass Effect 2, and the actual execution of the mission and story is really enjoyable. On the downside, being familiar also shows its flaws, such as a lack of dialogue, crappy Hammerhead combat, and everything ending in a shoot-out.
But its overall quality is high, and if you're a fan of the game it would be hard to not enjoy it.
