Critical Miss in Hyperspace

Traveling through hyperspace ain't like dusting crops, boy! Without precise calculations we could fly right through a star, or bounce too close to a supernova and that'd end your trip real quick, wouldn't it.

So, we've already played five game sessions of Star Wars 2020 with the basic space rules I posted previously. Those included travel times and fuel costs of hyperspace travel.

That's fine for when everything goes as planned. But things going as planned is boring. Now let's spice things up with some new rules inspired from Galaxy Guide 6: Tramp Freighters

CP2020 Skill Checks

Hyperdrive Mishaps

When making a jump, the PC should make a skill check for their Hyperdrive Tech skill i.e. 1d10+Tech+Hyperdrive Tech at the appropriate difficulty:

• jumping on known hyperlanes within a sector, make an Easy roll
• jumping between sectors on known hyperlanes, Average roll
• under stress or preoccupied, bump up the roll by one level
• jumping within the sector or between adjacent sectors with no known hyperlane, bump up the roll by one level
• if they are trying to jump from within another ship while a Rathtar tries to devour their ship, make a Very Difficult roll



Hyperdrive Types

• if they are trying to jump into a planet's gravity well to avoid the planetary shields, make a Nearly Impossible roll 

Hyperdrive Modifiers

The more advanced the hyperdrive, the harder it is to operate. As such, add a modifier to the roll needed:

• x4 -2
• x3 -1
• x2 +0
• x1 +1
• x1/2 +2

Mishaps Table

Mishap Severity

If the player misses their check, a mishap occurs. First determine mishap severity

• Minor Mishaps: Check missed by <=5
• Moderate Mishaps: Check missed by <=10
• Catastrophic Mishaps: Check missed by <=15
• Fatal Mishap: Check missed by >15

Roll 1d6 on the appropriate chart to determine what mishap occurs. Unless you got a Fatal Mishap that is. In that case you flew your ship straight through a star or something similar!

Playtest

Well, we'll have to give these rules a playtest next game session. I'll let you know how it goes! Hopefully without too many fatalities!
