It seemed kinda cool I remember being posted here but EVERYTHING was done serverside making the game so laggy it was unplayable. It was an MMO of sorts and you started on an empty planet walking around. I don't remember much about because I couldn't loving play the thing it lagged so much. It almost seemed like it was trying to be no mans sky before no mans sky
Found:Shores of Hazeron
Edit: Okay there are these two other games I'm also looking for. They were both made by the same person, both side scrolling shooters. One game was horror setting and VERY red like everything in the game was red and bloody. You had a space suit and it seemed like you were slowly descending into some kinda lab killing monsters.
The other game that was on the same engine and was a 2D sidescroller that was similar to GTA, you would go around killing random people and taking missions in a futuristic city. They both were games you had to download. I swear the website was three numbers then a name (123Somename.com)
