Basic Fire Fight Sketch

I have some basic ideas for an X-com based combat system.   My thoughts were to make it into a good miniatures game first, and then see where RPG elements might come in.  I switched X-com's percentage basis to a d6 system, where mods are only ever +/- 1 or 2.

Here's the basic hit roll idea:

FIRE COMBAT

 

The Attack Roll:

Each attack requires a d6 roll equal or exceeding a target number based on distance from the attacker to the target.

RANGE                                DISTANCE                           EQUAL or EXCEED

CLOSE                                 0 to 4”                                 3+

SHORT                                 4” to 1’                                4+

MEDIUM                            1’ to 2’                                 5+

LONG                                  2’ to 3’                                 6+

EXTREME                            3’ to edge of table            7+

 

Positive Modifiers

There are a number of positive adds to the die roll which can make success more likely

Expert Marksman                            +2

Target Totally Exposed                   +1

Height Advantage                            +1
