[h1] Rock solid mix between RTS and TD. Protect main drill until it gather enough minerals. Place towers and your captain on the field. Destroy rocks to place new drills and increase resource mining. Towers and captain can be moved anytime hence RTS element. During gameplay orbs appear which contain 3 random perks but player can only choose one. Perks might improve towers, captain or contain bundle of new towers to build. Air strike can be used from mothergunship to obliterate swarms of incoming creatures and cannons can shoot freely anytime where the cursor is, ammunition replenish itself over time. Plenty of different missions like 4 minutes survival, boss base assault, where you have to protect and escort nuke to enemy's base. In some missions you can control mech and grab huge gold nuggets and throw them in the well or just protect excavator until it finish resource farming. After each successful mission upgrade equipment on the skill tree then move on to the next mission. Also terrain is changing to some degree making some spots filled with acid and yes, it affects where towers can be placed safely. Game gets intense. [b] What I would like to see: + More terrain destruction +…

Firstly, I didn't realize it had AI voices and images when I first got this, so pretty disappointed in that. If they removed those afflictions to the game, it'd be a pretty neat Roguelike TD game. There is something very satisfying mowing down hordes of foes, and the Roguelike gameplay is helps make you feel more powerful. Not the biggest fan of the mech missions though. The reason I don't recommend this is due to the use of AI, if that gets removed than its good. But until then, don't support the game.

The AI voice actors are horrible and the AI generated music is way too obvious. The game could be fun, but the AI slop completely ruins it.

Controls are so random. Sometimes you drag to select, sometimes you drag to move. Sometimes you right click to move.

AI voice-acting is insufferably bad
