Some people complain that accuracy of enemies is too high and it is hard to survive even when running from one to another cover position. ME2 Enemies accuracy is indeed quite pinpoint (more precise than in ME3 and ME1 ) and with this mod you can tweak it. You will have bigger chance to stay alive while under enemy fire.

Tweak number 1 (Enemy accuracy modifier ):
Difficulty levels have different shooting accuracy of enemies. Insanity have highest, hardcore is behind it, then veteran and lowest accuracy is on lower levels. 
This mod allow you to choose accuracy from whatever difficulty level you want. Not matter what difficulty level you play you can tweak it to have accuracy from different difficulty level. So are 4 options:

• lower (it change enemies accuracy level to accuracy from lower levels - so whatever difficulty level you use, the accuracy will be from lower difficulty levels )
• average (Veteran accuracy on all difficulty levels )
• high (Hardcore accuracy on all difficulty levels )
• higher (Insanity accuracy on all difficulty levels )
  

Tweak number 2 (Enemy accuracy while move and when aiming at moving targets ):
File where I tweaked accuracy of enemies (less accuracy when enemies move and when they aim at moving targets ). There are 2 versions:

• tweaked - enemies while moving are less accurate. They also less accurate when their targets are moving. Also their accuracy on medium and long
  range is slightly reduced.
• lighter - the same what above but smaller changes
  

(I recommend normal version first - "lighter" version is just in case )
This method of tweaking and this one below are prone to bug (possibility of freezing enemies ) although I made it without overdoing values so possibly this bug never occurs. 

Tweak number 3 (Enemy accuracy slight nerf at medium and long distance ):
File where I tweaked accuracy of enemies (slight nerf for medium and long distance accuracy ). There are 3 versions:

• medium+long - enemies accuracy on medium and long range is slightly reduced.
• medium - change only for enemies accuracy at medium range
• long - change only for enemies accuracy at long range
  

ME2 still will be cover shooter but with those tweaks you have some chance to stay alive while moving to another secure position than be instantly shred when you leave cover (this isn't any ridiculous nerf for enemies so it will not help you much when there is bunch of enemies close and ready for you ).
