Are there any Half-life fans here?But anyway check this video at first It should be noted that this game is powered by Unreal4 but not Source.
Unity is capable of more than what we are seeing in the current game. Issue being, at the moment, that the dev team is small, and they are tackling what they can with the team they have, and are doing a great job! Fingers crossed, that in future they can really expand the mechanics to include more detailed interactions with objects and the environment. I have high hopes for what this game can be. Long live Empyrion!
