Hello again, We continue #Blocktober with another section we’ve shown off previously, the Xen cave. This part shows up after last week’s arch island, and exists in the same “badlands” biome. The goal was to call back to the original Half-Life, where water and life collected more on the interior of the Xenian land formations. [h1]Concepts[/h1] The initial concept by Xen Lead Chris Horn was to have a bridge, built by the scientists in order to cross the dangerous water. The bridge would mysteriously have a section missing and the player would need to long jump the gap in order to proceed.

This would create a risk vs reward scenario as the player would have to jump over water that MAY (OR MAY NOT) contain Ichthyosaurs.

There was little chance that the player would fall into the water and it didn’t encourage exploration, due to how direct the player path was.

Working as much as possible with our existing geometry, we forced the player to long jump between platforms, added more obvious resources for the player to find through exploration, and made the path to the exit much more indirect. This lets the player take in more of the environment and makes them feel like they are progressing through a challenging environment, instead of simply following a line.

The Level Designers did a great job of building new gameplay out of the shape we had already created. A great example of “creativity through constraint”. [h1]Iteration[/h1] Things start to come together here with better lighting, some stalactite placement, and underwater foliage props.

You can see in the image below (brightened for visual clarity) that we lowered the ceiling and the height of the outcroppings on the left and right of the player’s view.

This is a design process that we have followed throughout the entirety of Xen. After these revisions, we handed the scene to Level Designer/Artist Spencer Rose to push it up to the quality of something that was worthy of a public screen shot. He further sculpted the displacements, propagated the cave with assets made by the art team, and used lighting to guide the player through the scene; for instance, making the hole in the ceiling stand out with lighting and volumetric rays (which subliminaly point to the cave exit). He also tweaked the water to look more “alien” and unique. The new water added some much needed contrast to the environment.

More to come for #Blocktober!
