In the end, Stellar Impact is a really fun and surprisingly deep game that delivers a pretty good tactical experience. Unfortunately, it will most likely fly under the radar for most players due to its stronger competition. To reiterate, despite this being a gem of an indie game, it’s quite difficult to recommend Stellar Impact, even for its entry price of $10, when there are a number of great alternatives in the same genre, namely DOTA 2 and League of Legends, both of which are completely free to play. Your desire to play this can only be influenced by how much the sci-fi concept appeals to you. But either way, if you’re looking for something different in this genre, then this would be a good choice.
Hardcore Gamer: For a minimum of about $5, you can get Thunder Wolves, Stellar Impact, DIVO, 100% Orange Juice (which will sadly not aid you with cold recovery), and Apple Jack 1+2 (which offers up platforming action and doesn't taste like apples.)
The Indie Jam Bundle gets you the shooter Dead Horde, the RTS Future Wars, another shooter in the form of Greed, a tactical shooter in Stellar Impact, Grotesque Tactics: Premium Edition, the physics-based first-person game Twin Sector, Unstoppable Gorg, and the zombie-filled Trapped Dead for $5.50.
