the 40 days is NOT impossible.. you just need to manage your money properly, learn to RELOAD your weapon when there arent any enemies (not just empty your clip) and buy SHIELD generators. im on day 44 right now.
Its nice to show what the monsters are resistant to... but more importantly... it would be nice to see on the bottom half of the level squares what they are WEAK against.
most of your turrets just sit there... you only ever play with one turret unless they are plasmids.. plus its lame that they have "extra" content which they expect you to pay for. either make the game pay or free. its not that hard a concept.
