PROJECT KCX-F2
= Episode 2.5 of Pumo Mines =
! For all popular Descent II flavors !
Compatible with D2X-Redux, D2X-Rebirth, Chocolate Descent 2 & more
(not tested with MS-DOS Vanilla Descent II)

Set between the Kartsal Motivation and Muchikuche episodes from Pumo Mines, this mission is a complete remaster made from scratch of a very old mission of mine from 1999, known as “KCX-F2”.
Based on those old amateur-ish levels I decided to build them from scratch with my current level-building skills and new stuff like original music, robots and even some more gameplay concepts.

The new version called “Project KCX-F2” was made to fill the gap of the playerbase that doesn’t want or can play D2X-XL and Pumo Mines, but nonetheless introducing everyone to Pumo Software’s original universe, lore and characters while making it compatible with all Descent 2 versions and sourceports.

THE STORY: Fourteen years have drifted by since the fires of the Pumo Mines: Kartsal Motivation conflict were extinguished. Following the collapse of the Hosako Hegemony, a fragile peace has settled over the stellar systems. The PMC thrives, yet the ghost of Hosako tyranny still haunts the dark corners of the frontier. Pilkara, the PMC’s Tech Development Overseer and wife of Rubeas, the CEO of the PMC, has gone off-grid.
Using blueprints and code fragments provided by her old friend Pamer, she has assembled a black-ops R&D team; They are attempting to stabilize the remains of the so called Toleriah Device technology through their secret endeavour, codenamed ‘PROJECT KCX-F2’.
The project suffered a containment breach as a dangerous radioneural wave saturated the facility where the team was working, making all the automated robots go haywire just like it happened during the Mineral Valley incident.
Enter MD Aries5, an outstanding pilot who will take care of the situation by purging and containing the breach while also securing the KCX-F2 prototype device.

DESCENT : FULL STRIKE

Play the Descent saga as never before! This is the definitive way to play Descent, Descent II and Vertigo.
This mission and mod tries to unify and bring a bit of coherence to the Descent series as a whole. You'll able to play all your usual Parallax-made levels from First Strike, Counterstrike and Vertigo within a single mission file, but expect a couple of changes that makes of them a full unified experience.

You'll also encounter some 'new' but familiar foes that also 'glue' the entire narrative of the Descent universe. 😉
Includes an optional .DXA mod to enhance your experience and for a better gameplay feel.

NOTE: you may encounter a couple of issues with some Vertigo robots having huge hitboxes and not loading properly between levels in Redux, will be totally fixed for next official Redux version but you can use this version made by Arne in the meantime: https://pumosoftware.com/files/descent/d2x-re … x-1.1-pumo2.zip
