Gaming Trend posted their review of Ashes: Escalation and gives it a 90/100! "Well beyond simple DLC, Escalation polishes every aspect of the base game. The campaign is excellent, and the expansion of defensive and upgradeable structures helps ease in new players." http://gamingtrend.com/reviews/rise-of-the-ai-ashes-of-the-singularity-escalation-review/
