I'm working on an USMC campaign for PzC since last winter, and will release the first full version in a couple of days.
Those who also visit Slitherine's PzC forum may have seen the first teaser version already, it included the first four scenarios playing on Guadalcanal.
Now that I'm close to release the full main campaign of 14 scenarios I thought I give the folks here a little heads-up.
Some info:
1. The download will be somewhat over 100 MB. The mod needs to be activated with GME (please see here how to install: http://www.slitherine.com/forum/viewtop ... 47&t=27158).
2. You play the US Marine Corps, so you get to buy equipment in use with the marines. The Army is separate, and in a number of scenarios present as aux units. Your opponents are of course the air, land and naval forces of the Japanese Empire. Some smaller engagements aside naval battles play no major role, though coastal bombardment does get more important throughout the course of the campaign.
3. As said you start during Operaton Watchtower on Guadalcanal in summer 1942. Later battles include assaults on Tarawa and other Central Pacific atolls in 1943/44. In mid-1944 you get the invasions of Saipan and Guam. After some more scenarios the campaign will end with the invasion of Okinawa in 1945.
4. Overall the mod is using variable scales for unit and map sizes for different scenarios, so it is like the original game in that regard. The scenarios are meant to depict historical battles, but I don't aim to simulate everything perfectly. When in doubt I decided to give gameplay priority over accuracy.
5. Since there are lots of changes compared to the vanilla game, I included a customized version of the in-game library with additional info like campaign path, infos about unit traits and switches, upgrade families and more.
