Since the game doesnt ship with AA support you have to enable it yourself.
First download a nice free app called Nhancer from http://www.nhancer.com/
Run the program and create a new profile. Add masseffect.exe and masseffectlauncher.exe to the executables list.
On the settings panel click enhancements and enable antialiasing. Choose whichever settings you'd like. Next click the compatibility tab and check the 'antialiasing compatability' box. From the drop down list choose '00000145: AA & HDR'.
Run the game and enjoy the smooth lines
Works with every other UT3 engine game too with a little tweaking of the settings.
