Old splash
1. Open your localisation .pack (e.g. ‘local_en.pack’) with the Pack File Manager[sourceforge.net].
2. In the left-hand menu, expand the main .pack tree. You should see 4 directories: ‘facefx’, ‘font’, ‘text’ and ‘ui’.
3. Delete that last one.
4. Tick ‘CA Packs Are Read Only’ in the Options menu.
5. In the pop-up window, select ‘I’m not afraid, coward!’.
6. Save the file.
7. In the Files menu, click ‘Add’ -> ‘From Pack…’.
8. In the new window, find and open ‘old_splash.pack’ in the game’s ‘data’ directory.
9. Right-click its name in ‘PackBrowseDialog’ and click ‘OK’.
10. Save the file.
11. Exit the Pack File Manager.
12 (optional). Run the game, behold the old Roman backdrop and feel xenopatriotic.
Note: the ‘mod’ (‘old_splash.pack’) does nothing by itself, so keeping it ticked in the launcher is unnecessary.
