Fantastic game that I keep coming back to over and over. Tremendous replay value, great graphics, excellent audio and killer gameplay. I'd buy any game from these guys, seriously.

Great game, the campaign was a nice experience, some harder levels some easier. Will try a skirmish shoon, shame there is no multi-player but then again how can you defend vs other player?

Is this the best tower defense game in existence? No. Is it a GOOD tower defense game that provides the right amount of entertainment for the price? Hell YES. There's exactly the right amount of complexity and challenge here to be a really entertaining foray into the genre. I especially appreciated the addition of crew as an additional aspect that you'll need to manage in order to be successful. It's not enough to just build towers where the enemies will be coming. You'll also need to build power relays to power them, and assign crew members to man them. In addition to towers, you'll need to build a number of other support buildings to harvest resources and upgrade your towers. The game seems very simple on its face, but once you start getting into the later levels you'll find that you need to manage your resources and time very carefully in order to succeed. Excellent game. If they made a sequel, I'd buy it.

A tower defense-style tactical game where players deploy and manage units to defend against waves of enemies across different maps. The core gameplay is enjoyable, with each map presenting slightly different tactical challenges and encouraging basic adaptation. Unit progression exists through leveling marines, which adds some attachment and incremental growth over time. However, the game lacks meaningful meta-progression or unlock carryover between missions, which severely limits long-term engagement. Once the available content is understood, players are forced to repeat similar strategies without meaningful variation, leading to rapid fatigue. Overall: Solid short-session tower defense undermined by missing progression systems (2.5/5)

This has so much potential... but like everyone has said repeatedly: There is no room for personalized strategy and only one path to win and then rinse and repeat. It is an unimaginitive grind. The devs aren't reading these reviews and this game is dead. You have been warned.

The game is pretty nice, i for one like to play it casually and i think it's playable for all skill levels. The biggest thing i hate about the game is that there's no BORDERLESS WINDOWED mode so i have to either play in a much smaller window if i want to be able to play music on my second monitor and do quick alt tabs or just focus on the game and pause it anytime i have to do something there no matter how quick :(
