We have bested over 40 levels in Q2. We have killed Shub-Niggurath, Chthon, and a pair of Vores in the original game. Yet now we face our greatest challenge yet! Can we hope to survive against Sparky the Shambler?

Yeah, very interesting name for a level. I am guessing Sparky refers to the Shambler due to the setup of the level and the idea of building up to fight the boss. Sparky is just a regular Shambler (what, you thought Q2 would for once have something custom beyond textures?).

This level is basically another corridor run with very few rooms. There are two long corridors, though the first one just connects to the start. The second has a series of doorways giving you access to a Grenade Launcher to kill the Zombies and a Thunderbolt for Sparky. Connecting the corridors are two small corridors with two rooms each. The further rooms from the start have 25 Health, while the closer rooms are different. The right closer room has a Pentagram of Protection and the left closer room has more Cells, the latter of which will be needed to easily kill Sparky.
