@AndreOfAstora the game isn't pay to win at all, you can see proof from 'PPE' videos people post on youtube. Sure paying can help, but it's not required to advance in the game or get the top gear. A pet also helps, but mine is a maxed rare and I barely focus on it and I've never put money into pet food. Dedication and skill are all you need with this game.
+bhrider you can increase the chance for all rare unit drops with Zava Detector (Upgrade for tech center). Buying bonus content also gives a huge boost to chance of ultra rare drops. On the level after I bought my content, I got a darkness barrier and a Vira Ultamia. Its worth it combined with all the other stuff.
To everyone who is saying they want Enigmata Stellar war 2: Enigmata is the prequel to the Enigmata series. To make a Stellar War 2, and have it still fit in the time line, it would really have to go before this game, as another prequel. (It could go after both Enigmata games but that would make the order odd.) Also Roshan's kick started fell way short of his goal. Under bonus content, Enigmata 3 is also supposed to be coming soon. As much as I want it, it may be a while, if ever, until we see Stellar War 2
