Honeslty, it's fun but short. I've yet to play "Dome Keeper", so I really don't have a point of reference, and I have not played the "Deep Threat" DLC. Ending is lackluster to say the least, and the gameplay is repetitive. No point in a second play through. I enjoyed the gameplay loop (Mine, grab resources, upgrade weapons/ship/mech, fight wave, repeat) just long enough to beat the game, and I might consider getting the DLC.

In short, if you are interest in playing the game Get it on a sale, it goes below $5 very often (including at the time of this review).
