Cavetour B4

Added in some backwards brushes fo players can run backwards by mistake into areas that they've already completed - this should help keep them from getting lost.

No more work being done on this map unless someone finds a bug that breaks the gameplay.

Have converted the map over to a multiple stage map instead of a single round so that both teams have a chance to rest and strategize their next moves in the next stage.

Have made the changes suggested in the last play test.

Unless more items found in the next test, this might be the final version.

Fixed:

• everything noted from the feedback of the test game (except the introduction of multiple stages)

Added in more gameplay features:

• more directional arrows as players were getting lost and it was also requested
• 2 one way doors for blue at the lab entance as red defended to easily
• 2 oneway doors at lab exit for flanking routes at the bad choke - these lead towards red's final
• removed some health/ammo in final area to make it harder for red team to build
• changed 1 spawn condition - red doesn't move to final until cap 4 is taken (previously it was cap 3)
• fixed a missing respawnvisualizer
• added in dynamic arrows so defending red team knows which way the car is going left/right at the spit
• added in a ladder at 1st cap point to indicate to the red team that they are allowed on top of the roofs
