First Strike (BattleTech)
First Strike is a fusion of Alpha Strike and Reflex System.
Modifications to AS Cards
Divide the Internal Structure bubbles into two rows. The top row has half of the IS bubbles (rounded up), and the bottom row has the rest, as shown in the following examples:
Movement
The core conversion between Alpha Strike terrain play, and hex map rules, is 2” per 1 hex and 1” per 1 level of elevation. A unit that can move 14”j can therefore move up to 7 hexes on a map.
Combat
Weapon attacks may be attempted at or within range brackets in use: Short (0-3 hexes); Medium (4-12 hexes); Long (13-21 hexes) and Extreme (22-30 hexes). Physical attacks of all types can only be performed between units that are in the same or adjacent hexes.
Roll To Hit
The attacking unit can make one or more attacks depending on the damage value for the range bracket in question. The damage value is divided into two-point groups (if the damage value is odd the last group is a one point group), and each group is a separate attack.
To execute an attack, the controlling player rolls xD20 for each unit and compares the total to the modified to-hit number. If the dice roll equals or is less than the modified to-hit number, the attack succeeds. Otherwise, the attack fails.
Applying Damage
Damage is applied in vertical sections, starting from the right (in the examples below sections are numbered from 1 to 5).
Check off one armor or internal structure bubble for every point of damage delivered against the unit, until all damage is applied.
If only armor bubbles were checked off, roll once (2D20) on the Critical Hits Table for each attack.
If any Internal Structure bubbles were checked off, roll once (2D20, +3 for each Struckture bubble checked off in one attack) on the Critical Hits Table for each attack.
Note that some weapons may provide a modifier for the Critical Hit Roll.
