Nightdive Studios has shared footage of System Shock's alpha test, showing off new textures and environments from the rebooted classic.

Polygon reports the alpha is currently invite-only and available chiefly to those who pledged $750 or more to its Kickstarter campaign .

"Welcome to the System Shock: Adventure Alpha! Backers will be able to freely traverse Citadel Station, pick up items, listen to audio logs, read emails and complete the game’s objectives from start to finish," explained the studio.

"These are the original textures and not final art," the video description adds . "Not only will these re-tooled textures make the Adventure Alpha more interesting but it will provide the team with a blueprint of how to approach updated art, lighting, level design, and more."

After a little confusion in the comments, Nightdive added: "These are the original levels using the original textures from the game. The purpose of this alpha is to rebuild all the levels 1:1 and be able to complete all the objectives necessary to finish the game. There will be many more updates, please stay tuned."﻿

Nightdive Studios' 2016 campaign to crowdfund a remake of System Shock was a huge success, smashing the $900,000 goal and raising $1.35 million.
