The Ironclad MK-IV Gunstrider is a medium-class combat mech weighing 50 tons. It moves up to 8 squares per turn and has no jump jet capability. ARMOR: The Gunstrider has 180 Armor Rating. Damage reduces this total. When armor reaches 0, further damage applies to the mech's internal structure (treat as 60 HP). HEAT: The mech has a Heat Capacity of 28. Track cumulative heat each round. Double Heat Sinks reduce total heat by 4 at the end of each round. If heat exceeds capacity, the mech shuts down for 1 round and all heat resets to 0. WEAPON SYSTEMS: - Autocannon-10 (Right Arm): Range 18 squares. 3d10 ballistic damage. Generates 5 heat. - Medium Pulse Laser (Left Arm): Range 12 squares. 2d6 energy damage.

Each round, a pilot may fire any number of weapons. Sum their heat generated and add it to the running total before subtracting heat sink reduction. SPECIAL SYSTEMS: Targeting Computer allows one damage die reroll per turn. CASE prevents catastrophic ammo explosion on overheat. Double Heat Sinks dissipate 4 heat per round. FULL BARRAGE: Once per combat, the pilot may declare a Full Barrage, firing all systems simultaneously at +4 bonus heat but with disadvantage on all attack rolls.
