While working on the mission modifiers, I've found a few game breaking issues that needed to be fixed.

This new version has these issue fix along with the new mission modifier system

Now missions have a chance to generate with a modifier that will chance how the mission plays out. The amount of modifiers that you will encounter rises as you progress through a run.

The current modifiers are:

Lessen presence, less enemies will spawn. Decrease money reward.
Vehicle can deploy, you can choose to deploy the Fortress APC or Sand Buggy based on character party. Decrease money reward.
Ambush risk, enemies will ambush you after a random delay. Slightly increase money reward.
Grunt party, more enemies will spawn and more basic enemies will spawn. Slightly increase money reward.
Sandstorm, decrease everybody vision range. Slightly increase money reward.
Landmines, spawns landmines that targets the player party. Increase money reward.
Artillery strikes, a constant artillery barrage targets the player. Increase money reward.
Enemy armour, the 5th mission boss for the faction appears. Killing it is not necessary unless it's a Seek and Destroy mission. Greatly increase money reward.
Lots of Elites, more elites will spawn. Greatly increase money reward.
Increased presence, way more enemies will spawn. Greatly increase money reward.

More modifiers will get added later on.
The current goal now is to add in the upgrade system and the shop. Another minor version will be released and these 2 are usable.
