Injured
Your Character's limb has been broken by incoming critical damage. There are different penalties for each crippled limb. All kinds of cripples can be healed using Doctor skill or by medical professionals in cities. An injury will cause the red "INJURED" indicator to appear on-screen in the upper left corner. You can hover your cursor over this to see what injuries you have.
Eye Damaged
This means your character has been seriously hit in one or both of your eyes. This affects your Perception.
The Character's Perception is lowered to 1, which means you have a very limited field of view - 23 hex. Your chance to hit a target is also lower than the chance you would normally have without crippled eyes.
Crippled Arm
Your character's right/left arm has been severely hurt, and cannot function well. If one arm has been crippled, you cannot use two-handed weapons. If both arms have been crippled, you cannot attack with [any] weapons.
With one arm crippled, your Character cannot use two-handed weapons.
Crippled Leg
Your character has crippled right/left leg.
With one leg crippled, your Character cannot run in Real-Time Combat; in Turn-Based combat one hex move costs 2 AP. With both legs crippled, your Character moves very slowly in RT, 1 hex at a time stopping in each hex; in TB Combat, one hex move costs 4 AP.
