General path to enemy respawn points data:
- NETBIO00.DAT > [r0xx.afs] > r0xx.epp
Header¶
Size of the header varies depending on the number of rooms included. Each respawn data chunk (room) can contain one or more positions.
For each room we have:
- 4 bytes roomID
- 4 bytes offset
Once room data ends:
- 8 bytes terminator FF
So the total size of header is n x 8 bytes + 8 bytes.
Example header of r40.epp (Wild Things)¶
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

---------------------------------------------------------------------------
We can see:
- Room 01 respawn data begin at offset 40
- Room 02 respawn data begin at offset 68
- Room 03 respawn data begin at offset 7C
- Room 06 respawn data begin at offset A4
- Room 0E respawn data begin at offset CC
- Room 12 respawn data begin at offset E0
- Room 13 respawn data begin at offset F4
At offset 38 header terminates.
Respawn point data¶
Structure is not yet completely understood!
Each spawn location represented by 20 bytes of data:
- 4 bytes unknown (seems to affect enemy type somehow. Edit: Actually, i think it indicates door ID where a zombie or hunter respawns)
- 4 bytes int representing X coordinate data
- 4 bytes int representing Z coordinate data
- 4 bytes int representing Y coordinate data
- 4 bytes int unknown, seems always 00 00 00 00 a terminator ??

General path to enemy route tracking points data:
- NETBIO00.DAT > [r0xx.afs] > r0xx.rtp
Header¶
Size of the header varies depending on the number of rooms included.
- 4 bytes number of rooms (roomCnt)
Depending on the number of rooms we have
- 2 bytes short for each room IDs
then
- 2 bytes offset for each tracking route
Size of the header is 4 + (2 x roomCnt) + (2 x roomCnt) = 4 + (4x roomCnt)
Example header of r40.rtp (Wild Things)¶
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

We can see:
- Room count 07 00 00
- 00 01 Elephant Restaurant
- 00 03 In Front of Elephant Restaurant
- 00 04 South Concourse (before Titan Enters cutscene)
- 01 04 South Concourse (after Titan Enters cutscene)
- 00 05 East Concourse
- 00 06 North Concourse
- 00 0C Elephant Stage
- 00 00 Tracking route offset 00
- 64 00 Tracking route offset 01
- EC 00 Tracking route offset 02
- 80 01 Tracking route offset 03
- 14 02 Tracking route offset 04
- 8C 02 Tracking route offset 05
- F0 02 Tracking route offset 06
At offset 1F header terminates.
Example route data of r40.rtp (Wild Things)¶
General outline of tracking route:
- 4 bytes tracking route data set quantity
- 4 bytes tracking route sequence quantity
for each route data set
- 4 bytes route start offset
for each route sequence
- 4 bytes route sequence offset
for each route data set
- 4 bytes position X
- 4 bytes position Y
- 4 bytes position Z
after route data sets, sequence beings:
- 1 byte source room
- 1 byte destination room
- 1 byte sequence steps quantity
for each sequence step
- 1 byte associating them to the route data set
Tracking Route 0

---------------------------------------------------------------------------
Using the above we can see:
Start address of first tracking route (TROFF_00) = HeaderBytes + TROFF_00 = 4 + (4 x 07) + 0x0000 = 0x0020
Tracking Route Data Set Quantity (TRDSQ) = 05 00 00 00 = 5 route data sets
Route Sequence Quantity (RSQ) = 01 00 00 00 = 1 sequence
Since there are 5 route data sets there are 5 offsets:
RDOFF_00 = 20 00 00 00
RDOFF_01 = 2C 00 00 00
RDOFF_02 = 38 00 00 00
RDOFF_03 = 44 00 00 00
RDOFF_04 = 50 00 00 00
Tracking Route Data Sets (TRDS):
TRDS_00_Address = TROFF_00 + RDOFF_00 = 0x0020 + 20 00 00 00
TRDS_00_X = 00 18 51 46 = 13382
TRDS_00_Y = 00 80 A7 42 = 83.75
TRDS_00_Z = 00 94 66 46 = 14757
TRDS_01_Address = TROFF_00 + RDOFF_01 = 0x0020 + 2C 00 00 00
TRDS_01_X = 00 44 52 46 = 13457
TRDS_01_Y = 00 80 A7 42 = 83.75
TRDS_01_Z = 00 84 6A 46 = 15009
TRDS_02_Address = TROFF_00 + RDOFF_02 = 0x0020 + 38 00 00 00
TRDS_02_X = 00 D4 5C 46 = 14133
TRDS_02_Y = 00 80 A7 42 = 83.75
TRDS_02_Z = 00 04 68 46 = 14849
TRDS_03_Address = TROFF_00 + RDOFF_03 = 0x0020 + 44 00 00 00
TRDS_03_X = 00 D4 5C 46 = 14133
TRDS_03_Y = 00 80 A7 42 = 83.75
TRDS_03_Z = 00 04 68 46 = 14849
TRDS_04_Address = TROFF_00 + RDOFF_04 = 0x0020 + 50 00 00 00
TRDS_04_X = 00 48 51 46 = 13394
TRDS_04_Y = 00 80 A7 42 = 83.75
TRDS_04_Z = 00 90 64 46 = 14628
Since there is 1 route sequence there is 1 offset:
RSOFF_00 = 5C 00 00 00
Route Sequence (RS):
RS_00_Address = TROFF_00 + RSOFF_00 = 0x0020 + 5C 00 00 00
Source Room ID (SRID_00) = 03
Destination Room ID (DRID_00) = 03
Sequence Steps Quantity (SSQ_00) = 05
Sequence Step 00 (SS_0_00) = TRDS_00
Sequence Step 01 (SS_0_01) = TRDS_01
Sequence Step 02 (SS_0_02) = TRDS_02
Sequence Step 03 (SS_0_03) = TRDS_03
Sequence Step 04 (SS_0_04) = TRDS_04
