YMMV / Blue Shift Focal Point

• Awesome Art: This chapter houses a neat looking section where Calhoun has to traverse a path that goes along a flowing Xen river. It's one of the more memorable parts of the game since a flowing river using Xen water texture is something that's not seen in any of the other Half-Life games.
• Hilarious in Hindsight: This Xen level is considered one rare example of Xen being done right, with diverse environments, logical labyrinths, and more tame platforming, compared to the original game's Disappointing Last Level syndrome and Opposing Force's minute-long visits, of them only one being mandatory. The Half-Life remake, Black Mesa, opts for a similar approach, on steroids.
• That One Level: This chapter is another level that takes place in Xen, whose levels in the original Half-Life are not viewed fondly. While "Focal Point" doesn't suffer from the same design problems as its predecessors, there's still a fair bit a platforming to do across large gaps, so the error of mis-jumping and falling into oblivion is still very high. There's also a maze of small tunnels that can be confusing for first timers. Finally, if that wasn't enough, there are no armor pickups in this level. Once your armor meter is fully drained, encounters with large mobs of enemies can quickly spell death, so you'll have to be very careful.
