Expanded Planetary Assault Rules

Planetary Assaults will be fought utilizing current NBT PA rules. Any 'Mechs that have not been destroyed may be used at any time.

 

Battle Specifics

Drop Zone Stage (Stage 1) - Foothold

The DZ Stage models the initial drop by the Attacker to gain a foothold on the planet. The number of battles that are successfully completed determines the degree of success. See above. The Defender has the option of forfeiting these drops. If they choose to do so, the PA tracker automatically begins in Slot 4.  If either team wins all 3 LZ drops, they will receive their opponents ForceDec.

The DZ stage of the PA will be fought as 3 battles, following the following rules:  5-8 pilots per side; 400 tons maximum. Surviving 'Mechs carry over. Disconnects and accidental team kills count.

The attacker must choose the map on which the DZ drops will be played. This map will be used for all 3 DZ drops.

  • The Attacker must kill all of the Defender's 'Mechs or it is a loss for the Attacker.
  • Attacker wins 0 DZ battles - PA goes directly to Forced Retreat Stage
  • Attacker wins 1 DZ battle - PA begins at Slot 1  (PA drops begin)
  • Attacker wins 2 DZ battles - PA begins at Slot 3 (PA drops begin)
  • Attacker wins 3 DZ battles - PA begins at Slot 4 (PA drops begin)
PA Drops (Stage 2) - DZ to Slot 9

This is where most of your Planetary Assault battles will be fought. They vary in size and number from drop to drop, representing the constantly changing face of a huge battle like a PA.  The second stage of the PA will be fought in "Skirmish" with a 60-minute time limit.

  • The PA Tracker will randomly determine the drop tonnage and map for each drop in the PA. It will list the current drop, as well as the next 5 drops.  These tonnages range from 300 to 600 tons.
  • Teams may use between 5 and 8 (inclusive) pilots per drop, as long as they do not exceed the current drop tonnage.
  • Partial Destruction & Battle Tie Rules apply.
  • Surviving 'Mechs carry over for both teams.
  • The PA may be resolved by plain attrition, never reaching Siege Stage. If either Attacker or Defender finds themselves out of 'Mechs, then the side with 'Mechs remaining wins the planet.
  • A drop win for either side will result in the PA Tracker moving one slot (up for Attacker, down for Defender). If the drop win is a shutout (having lost none of your own 'Mechs, while annihilating the other team), the PA Tracker will move 2 slots in the appropriate direction. 
Siege Assault (Stage 3) - HQ

The Siege stage models the final push by the Attacker to gain control of the planet. Siege is played out as the best 3 out of 5 drops, fought in the "Assault" game mode. Time limit will be 60 minutes. The PA Tracker will randomly determine the drop tonnage for each drop in the Siege.  It will list the current drop, as well as the next 4 drops. These tonnages range from 400 to 600 tons.

  • Teams may use between 5 and 8 (inclusive) pilots per drop, as long as they do not exceed the current drop tonnage.
  • Partial Destruction & Battle Tie Rules apply.
  • The automation will choose a random Assault map from those available in the automation for each series of Seige drops.

If the Defender wins the Siege, Attacker is pushed back to slot 5 (to simulate the loss or decimation of the Siege force and the need to regroup). At this point the PA returns to the TA Stage.  If the Attacker wins the Siege, Defender is forced off planet with 15% of their remaining 'Mechs.  The PA is logged in the NBT automation as "Attacker Victorious". The Attacker may win the Siege Assault stage in two ways:

  • Destruction of all the Defender's 'Mechs
  • Destruction of a minimum of 50% of the tonnage of the other team & the Siege targets (all of them).  Only the 'Mechs destroyed to that point in the game are reported as destroyed.  In Siege type drops there is an option to report "Siege Targets Destroyed".  
  • Destroying the Siege targets before the 50% mark is reached will not move the tracker and will result in penalties (see FAQ.11).
Forced Retreat Stage

The Forced Retreat stage models the last-ditch effort by the Attacker to remain on the planet. Forced Retreats are played out as the best 3 out of 5 drops, fought in the "Skirmish" mode.  Time limit will be 60 minutes.

  • The PA Tracker will randomly determine the drop tonnage for each drop in the Siege.  It will list the current drop, as well as the next 4 drops. These tonnages range from 400 to 600 tons.
  • Teams may use between 5 and 8 (inclusive) pilots per drop, as long as they do not exceed the current drop tonnage.
  • Partial Destruction & Battle Tie Rules apply.
  • The automation will choose a random map from the current terrain set for each series of FR drops.

If the Defender wins the Forced Retreat, Attacker is forced off planet with 25% of their remaining 'Mechs. The PA is logged in the NBT automation as "Defender Victorious".  If the Attacker wins the Forced Retreat, Defender is pushed back to slot 5 (to simulate the loss or decimation of the defending force and the need to regroup). At this point the PA returns to the TA Stage.

 

Voluntary Retreats

Either Attacker or Defender may voluntarily retreat at any time. Battle will be logged as Retreat by the respective force. Voluntary Retreats always require adequate Jumpships are available in-system to take any 'Mechs off planet. If there are no Jumpships available, or not enough to hold all of the remaining 'Mechs, those 'Mechs become the property of the winner.

Voluntary Retreats must take into consideration a "safety zone"; that is, either force may retreat either before the PA begins or at some distance from their respective rally points. For example, in order for either the Attacker or Defender to retreat with 100% of their remaining force, the PA must be in TA Stage and between Slot 3 and Slot 8, respectively.

Attacker Retreat Options:

  • If the assault is in slot 3 - 10, they may retreat with 100% of their remaining forces.
  • If the assault is in slot 2, they may retreat with 50% of their remaining forces.
  • If the assault is in slot 1, they may retreat with 25% of their remaining forces.
  • If the Attacker retreats before any combat is fought, they will lose 15% of their attacking force. Those 'Mechs are granted directly to the Defender.

Defender Retreat Options:

  • If the assault is in slot 1 - 8, they may retreat with 100% of their remaining forces.
  • If the assault is in slot 9, they may retreat with 50% of their remaining forces.
  • If the assault is in slot 10, they may retreat with 25% of their remaining forces.

 

Best Out Of 5 System

DZ / Forced Retreat / Siege

Best Out Of 5 is tracked on the system above.  Each win will give a point for the respective team. First team to win 3 battles is the winner of the Best Out Of 5 Stage (Siege, Retreat). Note - This same system is used for the initial DZ phase to show battle progress.
