What is listed
Only changes with a described effect are listed. The Roblox experience record shows a later update timestamp without patch notes, and that timestamp is not treated as a balance patch.
What is on the Control Europe dated log?
- Aircraft carriers
Carriers were added on 3 April 2026. They need navy technology level 3, cost 525,000,000, take 120 seconds, and are countered by battleships.
- Formables can be reverted
Since 22 December 2025, the player who forms a nation can transform back. It is not documented whether that frees the formable for anyone else.
- Formable milestones
On 18 October 2025 the milestone track started paying titles and medals from formable progress. The announcement highlighted 10, 30, 50, 70, and 90 percent. The fuller table also pays 50 medals at 5, 15, 25, 40, and 60 percent of the 363-entry counter.
- Alliances and Update 19
Alliances arrived on 12 October 2025 and replaced one-to-one pacts. The October 2025 update also added alliance logs, invite search, a Max button on Send Support, leader kicks, Kingdom of Bohemia, and BRICS, including a title for forming BRICS on the world map.
- Formables added
Transformations arrived in August 2025. The exact calendar day is not in the notes, so this entry has no day-level date.
- Control Europe released
Hidden Studio released Control Europe on Roblox on 11 May 2025. The store loop is still: pick a modern European country, capture and upgrade cities, research, and ally or betray until you control the map. Private servers have Save and Load.
