I've just uploaded a patch to RTD:E. It includes some modifications to the game to make the learning curve a bit easier, make some elements less tedious, fixes a few bugs, and also add in some achievements.
The main changes include:
-Headshots are easier to preform on easy mode (should reduce complaints about low ammo).
-Standing still for a moment will make adrenaline recovery quicker.
-ID boss fight now includes a hint if you die a few times.
-Five achievements are available to be unlocked.
Please see the change log in the readme.txt for more information about what this patch changes.
If you find any bug with the new patch, please let me know, and I'll submit a new patch with a fix.
