I have recently played the Shadowrun Returns PC game and the expansion Dragonfall, quite liked the character system, and that got me thinking about playing Shadowrun tabletop too.

Before I buy the books, however, I would like to get an better overview of how combat works. I read that it's based on dicepools, but what I read seemed fiddly and complicated. So:

How does the basic Shadowrun SR4 combat mechanic work?

A good answer should include an example or explanation for a Street Samurai character firing his guns as well as a Mage or Shaman casting spells and a rigger directing her drone. I am not interested in decking/Matrix stuff, which seems to have it's own set of rules, unless your answer shows why this belongs in there too.

I am aware that Shadowrun 5 is out for some time, but I am mainly interested in Shadowrun 4.

I'm pretty sure no one's willing to give you what you consider a good answer because the areas you want detailed are distinct, complex subsystems, examples of which would be useless without knowing the game's basics. I urge you to take the suggestion of @mcv and download the quick start rules then come back for clarification. –  Hey I Can Chan Mar 17 at 16:27
    
+1 with above comment. That's about sixty pages of tables and rules to sum up, which would be quite a feat. It might be possible to find a "basic combat mechanic", but that would be pretty tough. –  Cristol.GdM Mar 17 at 19:23
    
Matrix don't really have it's "own" set of rules. It works the same way but understanding hacking requires reading yes. I wouldn't discard it simply because it's such a HUGE aspect of the game. At first, you can tell the players you'd rather not have a hacker PC and take the time to read it but I wouldn't simply ignore it. –  MrJinPengyou Mar 17 at 21:08

Basic rolls

You roll as many d6s as your Attribute + Skill for the intended action. Each dice rolling a 5 or 6 is a "hit". If there is a difficulty, the "net hits" are the amount on hits above that difficulty.

A player has to roll Charisma + Etiquette, with a difficulty of 3. His character has 5 in Charisma and 3 in Etiquette. He rolls 8 d6s, and 4 of them roll a 5 or 6. That's 4 hits, or 1 net hit.

"Basic" combat mechanic

1 - The attacker rolls the appropriate attack skill + attribute + modifiers.

A street samurai fires a single shot at a non-moving target. He rolls Agility + Pistols, for 4 hits.

2 - The defender then rolls the appropriate defense skill + attribute + modifiers.

This depends a LOT on how the target defends. For our example, let's say the target just rolls his reaction to jump on the side, for 1 hit.

3 - You then compare their results. If the defender rolls more hits than the attacker, or on a tie, the attack misses. If the attacker rolls more hits, the attack succeeds and the net hits is added to the weapon's Damage Value.

If the target had rolled 4 hits or more, nothing would have happened. The attacker rolled more though, so the 3 net hits are added to the weapon's Damage Value. The weapon had a Damage Value of 6P, it becomes 9P for this attack.

4 - If the attack succeeds, the defenser then rolls Body + Armor - Weapon Penetration. Each hit reduces Damage Value + net hits of the attack by 1.

The target has a Body + Armor of 7. The gun has a Penetration of -1. The target therefore rolls 6 dice, with each hit reducing the modified Damage Value by 1. He gets 2 hits, reducing the modified Damage Value to 7P.

5 - Finally, you apply the final Damage Value to the defenser as wounds (i.e. nothing if it is reduced to 0).

The defenser takes 7 wounds, and crosses 7 boxes of damage on his sheet.

This is the combat mechanic reduced to its "simplest". However, keep in mind that a LOT of modifiers and exception then apply, depending on whether the attacker or defender is moving (or both!), whether anyone is behind cover, the weapons rate of fire, who is already wounded, recoil, and so on.

Drones and Magic

Drones and Magic are both two extremely complex and detailed systems of the game, therefore it is almost impossible to sum them up in a couple of sentences. I will give some guidelines, but take them with a truckload of salt.

Drones have their own mechanic, but basically and in a lot of cases, there will be a hacker using his Mental attributes + hacking skills to attack/defend instead of standard attribute/skills.

As for Magic, there are even more things to take into account. In a lot of situations, spells will be cast using a Mental Attribute and the Spellcasting skill, and will be resisted either through Willpower or normal defending attributes. They also cause damage to the casters. Remember though that there are a LOT of different spells, of ways to cast them, as well as Adepts and Spirits.

A word of warning: the character creation/advancement system in Shadowrun Returns is not even remotely related to anything in any edition of Shadowrun. (In fact, I think it's not very good, though the game itself is a lot of fun.)

If you want to get a free look at the 4th edition rules, download the Fourth Edition Quick Start Rules.

Personally I'd recommend the 5th edition over the 4th; it's a nice mix of the best ideas from 4th edition with more of the atmosphere and good ideas from previous edition that fell by the wayside in 4th. But do whatever strikes your fancy; 4th edition is a very fine game too. In case you're interested, here's the Fifth Edition Quick Start Rules too.
