SilverTM has uploaded the final version of Project Lambda, you can download it over here. This is an unofficial remake of the first chaper of Half-Life, which is basically the intro/train section. There's not a whole lot to do, but it does give a nice impression of how Half-Life would look like in Unreal Engine 4. SilverTM promises work on the second chapter will start if their video gets 100k likes.
What’s really interesting here is that the team will work on the game’s second part in case this demo is downloaded and played by a lot of gamers. Now before getting overly excited, you should temper your expectations as this first part took a lot of months to complete, so don’t expect to be playing its second part anytime soon.
On the other hand, it’s really amazing that the team has released this demo to the public. Normally, most teams or artists do not release their fan remakes/recreations to the public. As such, we strongly suggest downloading it, especially if you are die-hard fans of the Half Life series.
