Interstellar Marines used to be one of the most promising first-person shooters which sadly died due to a lack of funding. It's limping along, with a new video to show off a new enemy.
The enemy is a Recon Drone, which will come with Update 28, take a look:
More about the Drone:
Introducing the Recon Drone, which will be introduced in Update 28 in both Cooperative and Wargames as a new enemy. The Recon Drone will have various abilities, including being able to call in reinforcements to your general location in the form of CTRs as well as being armed with mounted weapons.
Looks and sounds like it could certainly spice things up a bit! I haven't seen them post yet when Update 28 will be out, will keep you posted.
Honestly, I still think Interstellar Marines is more interesting than a lot of FPS titles coming out even recently, it has such a fantastic atmosphere and the game mechanics are pretty solid. I really do hope it sees a resurgence in 2019. Every time I jump in and manage to get a game online, I always have a good time.
