The main task of such add-ons is not the introduction of new graphic technologies, not the addition of new functions or systems (although they are still experimenting with them at this stage), but delving into the plot, the ability to tell and show what did not fit into the main game and should be told before the next part. These will definitely involve new places and battles. This happened with Half Life 2: Episode 1. A good addition that prolongs the enjoyment of the second Halfa. This is not even the middle of the whole journey. Will there be more...
