FLASHBANG- Core Rules

FLASHBANG is a game I cooked up while thinking of new and interesting ways to use the OSR playstyle and general gameplay in other settings and time periods. FLASHBANG is a game about tactical modern day "dungeon crawling", your party plays as SWAT.

Out of all the rulesets and complete games I've ever made, I'm pretty happy with it. Probably one of my best, due to its fast speed and simplicity.

Character Creation

You roll 3d6 for each stat. If you're the best of the best, you get 4d6 drop lowest instead.

[B]ody is your physical strength and toughness.

[R]eaction is reaction time to fire weapons.

[E]ducation is knowledge skills.

[A]gility is avoiding gunfire.

[C]are is empathy and first aid skill.

[H]eroism is luck and heroic stunts.

Classes

Once you roll your stats, time to choose a class.

Pointman uses point-blank weapons.

They get +2 to-hit point blank and +1 HP.

Their maximum AC is 18

Specialist uses support & special weapons.

They get +2 to the effects of special weapons.

Their maximum AC is 16

Their maximum AC is 14 until they change class.

 

Health & Damage

Your health points are 1d6 + body modifier.

The first time you are hit by a firearm attack that deals 1-5 damage, you are clipped and your armor is reduced by -2 AC. You are in pain and take -2 on all actions unless given an injection or first aid. Even after being healed or switching your armor, you still count as clipped and the next roll does normal damage.

Any roll of 6 or more is considered a lethal blow, usually a headshot. If you drop to 0 HP, you're out but might be saved if a professional (not medic) EMT treats you. Anything under 0 is death.

Combat

Whenever you shoot with a gun, roll d20 + reaction modifier vs the target's AC + cover. On a hit, you roll the gun's damage. On a miss, you must reload. Roll 1 to jam your weapon.

Point-blank attacks are done with fists, melee weapons, or point-blank firearm weapons. You just roll d20 + reaction modifier vs the target's AC, no cover bonus.

Your AC is determined by your armor + agility modifier and has a maximum based on your class. If you switch armor with a dead person that's better then your own, your max is the cap.

You can do field first aid. Heal 1d2 + care modifier as long as you makeshift materials.

Cover grants bonus AC to your character, avoiding the chance of them getting hit by gunfire. Cover from furniture grants +2 AC per person it would take to lift it. You can grant covering fire by shooting at any enemy that could shoot at your allies. Roll your weapon's damage and add that to your friend's AC as they move.

Heroic Stunts

To get a hostage to do anything risky, jump from rooftop to rooftop in hot pursuit, or throw a live grenade back at the guy who threw it, roll a d10+heroism modifier.

Normal target number is 6.

Negotiation

Criminals will make demands, usually on radio. If you don't give in to demand officer must roll 2d6 + leverage. If under number of hostages they will kill one. If you give demands the criminals get;

Random Demands- Roll 1d4

[1] Live getaway car- some criminals may escape.

[2] You cannot use long rifles for 20 minutes.

[3] Food, drugs, porno, etc. Injuried criminals reroll their hit dice.

[4] Craft supplies; They make a boobie-trap.

Unlike in real life, police cannot 'trap' these options.

Leverage

Each demand you give in to the criminal grants 1 leverage. Leverage can be used to free one hostage from the bad guys, or could be turned in to get one near the window.

You get -1 leverage if you kill one of the criminals. Negative leverage subtract from your negotiation rolls to avoid them killing more hostages.

Grenades

Everybody gets 2 grenades on a mission. You can scavenge other grenades as they come.

Roll 1d4 twice or pick 2

[1] Flashbang: Enemies stunned for 2 rounds.

[2] Gas: Enemy must move in 1 round or take 1d4 damage from gas. Gas damage is not lethal, but knocks you out if you go to 0 or less HP.

[4] Smoke: Grants +3 AC as cover bonus
