Capsule Shooter 3D:

In Brief:
Capsule Shooter 3D is a first person deathmatch shooter made with Unity, using Unity assets that I've seen in several Unity based games. In this game you can either join someone else's server or create your own.

I booted this game up several times over several days and there was never anyone online; that said, if you have a couple of friends, you could always arrange to play at a specific time and create a room so that your friends could join.

Presently there are only two maps to play, one of them a geometric platform and one set in a small village. The developer has said more maps will be added and possibly other modes of play; so, we may see this again sometime in the future?

You get three weapons to use with unlimited ammunition that are selected using the mouse wheel or the numbers 1,2 & 3. Movement used the WASD keys. To leave the game I had to use Alt + F4.

Conclusion:
Unless you have a couple of friends or more to play with you, this is a pointless game as I never found anyone online after trying several times over the last week. Even if you did find someone, one of the maps is really boring and the other has limited play before it also becomes boring. There are far better free to play first person shooters available on Steam.

Notes on Security
I scanned a zipped copy of the installed game using Virus Total and it found zero hits from 62 antimalware engines. You can see the installed games scan HERE.
