LEGO

I play a fair bit of Dungeons and Dragons style RPGs, mostly GURPS. Some colleagues and I recently generated a sort of Turn based, mass combat combat system based on GURPS rules  using LEGO.  I've posted our rules (works in progress) below with some photos. Let me know if you have any questions, comments etc. I'll be posting more info about our other rolling sessions soon. If you are interested in some of those you can check out my presence in the GURPS forums here:

Turn Sequence:

On a player’s turn, each unit gets 3 seconds. 

ACTIONS

Each unit gets 3 seconds per turn

1 second actions: 

• Ready weapon (every weapon must be readied before it can be fired. A weapon must be readied after moving or reloading)
• Aim (Weapons can be aimed for accuracy. Without aiming a weapon is at -2 to hit. Aiming for 1 sec negates that. Aiming for an addition 1 sec adds + 1 to hit to a maximum of + 3). After a weapon has been fired the unit must aim again to compensate recoil. The recoil effect compounds. If a marine fires three times in a turn, without aiming, his first shot is at -2, his second at -4 and his third at -6.
• Fire. Duh
• Load (ATT’s must load their weapon after each firing. Eg. ATT loads his weapon, readies it, aims it and then fires.
• Each units Move score is equal to the distance they travel per second. A unit can move  3 x it’s total move score in one turn. Or move their move score, ready and aim their weapon etc.

CUSTOMIZING:

Vehicles and units can be customized or custom made. 

Base vehicle cost is 150. Enhancements and limitations can alter the vehicles cost. You can never spend less than 75% of a vehicles base cost through limitations.

- 40 pts doubles the number of total occupants (vehicles always hold 2 people as a default. A vehicle without a second person costs only 100).

• All vehicles base Move score is 4. 20 pts adds +1 to it’s movement score. For a vehicle that moves slower than 4 reduce 10% of the cost of the vehicle per -1.
• All vehicles have a base of 15 HT costing 10 pts / additional +1. For vehicles with fewer hit points reduce the total cost of the vehicle by 10%
• All vehicles have a base DR of 1. The same rules as Hit points apply.
• WEAPONS:
• Each weapon costs 100 points to add. Weapons are added as weapons with 0 Range.  A Short Range weapon costs 10 points.
  Medium Range costs 50 points
  Long Range costs 80 Points.
• it costs 50 pts / 1 Dice OR +1 of Damage. (Eg. For a weapon that does 1d + 1 damage it would cost 100 points.) To do multiple dice damage that is rolled separately, (rather than doing 3 dice damage you do 1 Dice + 1 Dice + 1 Dice) the cost is 60% of the total cost of the weapon. 
• Vehicles that fly cost 100 extra points. Vehicles fly at their Move score in any direction

ATTACKING INTO/OUT OF/ ON VEHICLES

• When attacking a vehicle, or any large object, a unit gets +1 to hit for every 2 passengers the vehicle can carry. (Eg. A vehicle with a max capacity of 8 gives a unit +4 to hit.)
• Firing from behind or into cover. Attacking a unit over cover/ from behind cover is difficult. 1 level of bricks between the attacker and subject is -1 to hit. 2 bricks is - 3 and 3 bricks is - 5. More than 3 bricks or shooting from a small window is -6 to hit. WHEN FIRING FROM BEHIND COVER: An attacker behind cover suffers no penalties except behind heavy cover. Behind 3 bricks is -1 to hit. 4 bricks or more is -3. 
• A unit gets attacking bonuses from cover only if they are positioned within half their move score from the object. (Eg. A Marine must be within 3 bricks  of a wall to avoid shooting over the object with the total penalty).
