· The player now has to pass through the underground area to get to the main central area. The underground area has been extended and connects with the large circular building. This includes a new large interior space that the player passes through. · Global game events can now occur sooner and now depend on player progress. · Enemy robots now inflict much more damage, encouraging the player to be more tactical. They can no longer just run past groups of them and hope for the best. Old saves can still be loaded for this build, but it is strongly advised to start new games as some of the changes will affect the overall gameplay.
