It's here! The latest version 1.21 patch for COMBAT MISSION SHOCK FORCE, CMSF
MARINES and CMSF BRITISH FORCES is available for download! This free patch
offers more than 60 improvements and a number of new features, such as:
an all new "Scenario Author Test" play mode
improved roads rendering on rough ground and steep slopes
improved calculations for tree damage from artillery and projectiles
dust being kicked up from firing small arms
additional Equipment Quality options and other TO&E changes...
...and much more!
Additionally, the v1.21 patch is now including updates for the base game and
all the modules in one single "intelligent" patch. No need to download several
patches - just one patch will present you with the option to update your base
game, base game + Marines, base game + British, or base game + both Modules at
the same time, depending on which games you own.
This patch does NOT work for players who have ONLY the base base, retail
version (Paradox or Gamersgate version), and no modules! A separate "Plain Jane"
v1.21 patch for these customers will be released in the future.
Here just a few highlights from the latest release:
Top gunner in a Humvee can use a personal weapon if his vehicle-mounted
weapon is out of action.
Powerful projectiles like sabot can penetrate trees and be slightly
deflected rather than stopped.
Roads are smoother when traversing rough ground or steep slopes.
Large rocks (flavor objects) are more of a deterrent to navigate over.
Updated behavior for artillery/air support time-to-target. Conventional
Red formation leaders are now allowed to call in artillery from batteries at
battalion level or below (e.g. light mortars).
Troops may be given simultaneous Hide and Face commands, but changing
facing often requires a soldier to change position slightly, during which time
he will not be "hiding".
"Scenario Author Test" may be selected as a Skill Mode (1-player only). It
will cause all enemy units to be fully displayed to the player, but not
additionally "known" to player's troops.
Small bullets kick up a tiny bit of dirt and dust when they hit ground.
Marines Module Only
US Marines sometimes have M203 grenade launchers instead of M32,
especially at lower Equipment Quality settings.
Added US Marine Mk11 sniper rifle (equivalent to Army M110).
British Module Only
Jackal GMG (aka grenade launcher) can now be found in the Fire Support
Section of the British Infantry Rifle Company, when the equipment rating is
good (otherwise they get a WMIK).
Gunner in LMTV will use his personal night-vision gear when appropriate.
LMTV carries more passenger weapons and ammunition.
Roads are smoother when traversing rough ground or steep slopes.
