The Bossdome is an alternate gamemode that is unlocked by beating the standard gamemode on HARD difficulty. Its purpose is to make battles more boss-centered, reworking them to be the primary focus at all times. Currently, only Pillarhead has had a rework.
Other minor changes:
- Made the difficulty notations in the campaign menu consistent with the ones in achievement descriptions
- Reduced the size of an unnecessarily large audio file
- Made minor changes in campaign start UI, including adding back buttons
