The only good point in this section is a sequence where Freeman apparently (it's a bit unclear) frees the vortigaunts from slavery, which much better sets up the events of Half-Life 2. The sumptuous vistas disappear and Freeman instead spends what feels like ages clambering through narrow pipes connecting power cables together and trying to find the path forward, which becomes progressively more laborious (especially when the path forward is sometimes just blindly hurling yourself onto a conveyor belt or standing on the edge of a bit of scenery that looks more like a bug than a clear path forward).

The section after the Gonarch is then mind-numbingly tedious. Even worse, the Gonarch is completely indestructible until you finally corner it in its lair, but no information is relayed to the player to confirm this, meaning a lot of ammo is wasted before you can finally kill the damn thing. For some reason, the Gonarch boss fight has now been increased in length several times over, with Freeman playing cat-and-mouse with the creature through an underground cave network full of flaming gas traps and not-always-clear paths forward. The infamous pendulous mobile testicle monster was a horrific revelation in the original game, but a bit of a chore to fight. Unfortunately, things get less impressive when the player encounters the Gonarch.


There's a few too many power cable puzzles in this part of the game, but nothing too outrageous. This part of the game is great fun, with a lot of thought that's clearly gone into how to make Xen better from a gameplay perspective whilst retaining its alien landscape and atmosphere. There's even some new enemies, such as underwater barnacles that pull you down rather than up, and infant houndeyes which now explode rather than erupting sonic blasts at you. The first half of Xen has been improved a lot with pacing and more focus on traversing larger environments through logical puzzles and ferocious combat, with a lot of the detailed platforming from the original release thrown out. Xen is more than twice as long as its 1998 incarnation and maybe closer to three times.
