Siege of Centauri is a fun tower defense title for a good price. While, visually, there’s more to be desired, it runs incredibly well despite the thousands of enemies that can flood the map as you place your towers in an oftentimes frantic and addictive mission to protect your colony. It's well worth the asking price.

While Siege of Centauri isn't a groundbreaking game by any means, it'll be appealing to fans of the tower defense genre. It does its job in doing justice to that niche despite a lackluster story and some technical issues. These things are fairly easy to overlook since the gameplay itself is fun.

Ultimately, Siege of Centauri is fine. Its mechanics are solid enough, it does everything else decently on-screen, and the pyrotechnics are spectacular to see. It just doesn't feel like anything special, from the abilities to the story to the units to the towers. It's the kind of game that you wouldn't mind playing but won't rush out to buy immediately, making this difficult to recommend unless you devour every game in the tower defense genre.

All in all, Siege of Centauri felt dull after only a few hours of play. The game isn’t bad in any way, it just doesn’t provide anything interesting to the people who’ve already poured hundreds of hours in the genre. The competition is also stacked with plenty of tower defence games available for free online or on your phone. Lacking a defining feature also makes it hard for me to recommend it to anyone specific, and there is also no online functionality outside of user-created maps and leaderboards. There was not a single risk taken and I didn’t feel a hint of passion in Siege of Centauri. If there ever was a game that felt phoned-in, this is it.
