# Sins of a Solar Empire: Rebellion \- Forbidden Worlds® DLC Summer DB entity ID: 21c3e489\-c8da\-4f29\-b61d\-3483551fece1 Steam App ID: 228601 The war between the loyalists and the rebels within the TEC, Advent and Vasari continues within the depths of Trader Space\. Yet, this sector of the galaxy has far more worlds and far more history than any of the factions are aware\. Survival forces each to expand into the unknown, discovering worlds of hazard, wealth, risk, and mystery\. Most ominously, the Trader factions have been loathe to expand to these worlds due to the dark myths that surround them\. Key Features: Four new planet types to colonize and exploit \(Barren, Ferrous, Greenhouse, Oceanic\), each created with beautiful high\-res textures\. New Planet Specialization System: Dedicate your worlds to either social or industrial output\. Devoting your planet to social improvements will increase its population and culture, at the cost of trade income and ship production\. Choosing an industrial path will limit your growth and culture, but make your planet a trading and ship building powerhouse\. 15 new research subjects allow the races to conquer and expand onto the forbidden worlds\. Discover 40 new planet bonuses during your exploration of the galaxy, unlocking the dark past of the Sins’ universe\. Unlock five new Steam Achievements and display your mastery of forbidden space\! ## Game information - Type: dlc - Developer: Ironclad Games Corporation, Stardock Entertainment - Publisher: Stardock Entertainment - Release date: Jun 5, 2013 - Coming soon: false - Free to play: false - Parent Steam app: 204880 - Genres: Indie, Strategy - Categories: Single\-player, Multi\-player, PvP, Online PvP, LAN PvP, Co\-op, Online Co\-op, LAN Co\-op, Downloadable Content, Steam Achievements, Steam Trading Cards, Steam Cloud, Includes level editor, Family Sharing - Platforms: windows - Website: Not collected - Screenshots: https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_bd932bdb282ec31aebb90a21950a1fe3d1494577\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_de4c15f75d5b7e07bbd10a0b146bff8c7c4a82bf\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_812e5cddc726ba51e6b0f714d0ef1cecc4ae6fde\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_4e262b2b3fff319d64664bbc966cbca81f19eddd\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_588eb3e3c0fadc38f0a7f2ede91ad562c03c2de8\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_ca64f728a7fe39c366d0cad13fe792231ed3e0a3\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_6a70f27c94ddc1059380da06eecc8fec1e632fb8\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_116bc071fa0cc603ca2ecb2b3fa9dc53449dc859\.1920x1080\.jpg?t=1770141633, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/228601/ss\_ddb92556e59b68be9d38fe57f407c10a1cf30657\.1920x1080\.jpg?t=1770141633 - Price: 499 minor units USD; discount 0% - Price country: US ## Observed metrics - Current players: Not collected - Steam review count: 51 - Steam positive reviews: 48 - Steam negative reviews: 3 - Steam positive percentage: 94.11764705882354% - Summer DB rating: No native votes Review filters: \{"language":"all","review\_type":"all","purchase\_type":"all","filter\_offtopic\_activity":0\} ## Player history [Seven-day chart data as Markdown](/api/v1/entities/21c3e489-c8da-4f29-b61d-3483551fece1/player-metrics?days=7&format=markdown) · [JSON](/api/v1/entities/21c3e489-c8da-4f29-b61d-3483551fece1/player-metrics?days=7) Chart values are hourly observed maxima.
