The Talos Principle: Road to Gehenna is more of the same variety of puzzles to pleasingly tax your brain… taking you to the point of frustration before finally clicking how you need to place that connector gem to release the next android. I am very happy to have more of this wonderfully realised world and existence… the Matrix for Androids!
But back to the original question "does it deliver?" Yes and no. I can see what it's trying to do and there are moments of fun, but for me it just lacked a degree of polish or something that would make me eager to get to the next level. Instead progression felt like more of something I had to do rather than wanted to do. I will no doubt play more in the future, but it doesn't have the same simple brainless fun that the classic C&C series did. A noble effort that many will find a great deal of fun in, whilst others might find it lacking something.
Overall if you've enjoyed the Might and Magic Heroes games before then you won't be disappointed, if you've only tried Kings Bounty before then I'd suggest jumping into Heroes VII it will seem familiar but also a little more "real" in style.
If Tower Defense isn't your style though, then give this a miss… the different genre elements do make it more interesting and entertaining, but there isn't really enough there to make it a lasting experience… play through is extended a little by having the four different characters but the experience is not sufficiently different with each one to really make it much of a draw to play again just to see a few different weapons or short cut scenes.
