Xenobiotic Xeranthemum is a level pack which contains 5 full-length (that might be an understatement) levels, all of which are themed after JJ1 levels: Diamondus, Turtemple, Tubelectric, Ceramicus and Technoir. Each level has its own set of enemies and the pack is characterized by taking multiple paths to open other paths in order to proceed.
Gameplay: 7/10
The first two levels are probably the best in terms of gameplay, the other three are not that far off though. Some unfair and unfun segments but it’s got an overall good level design. None of the levels have any coins to pick up and there is a considerable lack of secrets. The major flaw in this is how lengthy and repetitive it can get. I like the idea of opening different paths to proceed but in this level pack, it feels more like a chore after the first 3 levels. The level scaling is fine-ish, ammo placement is good and there are just enough carrots scattered throughout the level. Also, the level design can be a bit claustrophobic at times, though that’s not as much of an issue as it may sound. The ending was a bit anticlimactic as the boss was ridiculously easy to defeat.
Also, Archon, if you’re reading this, players can get stuck in the damaging red water in the Technoir level.
Eyecandy: 9.5/10
It is, overall, a great looking level pack. As far as I’ve noticed, there are no misplaced tiles. In some levels, the foreground elements are a bit tiring to look at (for example, the clouds in Turtemple). The introductory screens are pretty bad looking, though it might be because of JJ2’s palette limitations. Ceramicus was not very pleasant to look at because of how crowded the level can get. Speaking of an anticlimactic ending, the boss visuals were very poor: the robot boss can be clearly seen behind the “real boss”, there are some asymmetric lights surrounding the boss etc.
Music: 10/10
There is not much to say about it. The music is well chosen and it fits each level in particular.
Overall: 8.7/10
Do I recommend this level pack? Yes! However, I don’t recommend playing this level pack in one go. The levels are lengthy and can easily get repetitive after a while. Download and play this level if you’re looking for a solid JJ2 Single Player experience.
