It's much harder than the first one....especially when(spoiler alert..don't read if you wanna be surprised):
Spoiler [+]
The mission on Omega where you join these mercs but you have to double-cross them in order to save this dude Archangel(who turns out to be Garrus from ME1.) That WHOLE mission...I must have died 20x and I was playing on the normal difficulty..ESPECIALLY on the part where you have to force shutdown the doors before the mercs flank Garrus
All in all my opinion...
Pros:
- Story is 20x deeper and darker than the first
- Heavy Weapons
- The option to perform a Paragon or Renegade action when the indicator pops up on the screen...you can do it or you can just simply not do anything and let things continue
- New biotics look crazy
- The shotgun isn't cheesed out this time around, it actually works like a shotgun
- Shepard actually talks outside of the conversation options you pick for him/her
- Credits are a little easier to come by
- fights are very challenging, but feels rewarding when you finally do beat that tough enemy or boss
Cons
- the new HUD takes ALOT of getting used to, seems too...small
- Scanning planets for materials you might wanna buy upgrades with may be tedious for some
- All the different armors and stuff are no more, you just upgrade the one suit you have
