- Default crosshair appears where the laser sight hits environment, corpses, etc
- Locked crosshair appears when the laser sight hits characters (including the shooter)
- "Tunnel" is used by w8_mbo as a complement to the crosshair
- w2_sap, w5_sbg, w7_scc and w9_scr use it with no crosshair

0x158 - 0x1D7
- SECONDARY FIRING MODE
The only original weapon for which these fields are not all zero is w11_ba1.
They are the exact counterparts of the fields at 0xD8 - 0x157.
0x1D8 - 0x6DC
- PARTICLES
Every ONWC has 16 particle slots (80 = 0x50 bytes each.)
The number of slots actually used by the weapon is specified at 0xCA.
Offsets are relative to the beginning of a slot.

- Glow textures
- They're applied to the lower face of the M3GM's bounding box. The factors above are the ratio between the x/z extent of that face and the half-length/width of the glow textures. So if both factors are 0.5, the glow textures fit the bounding box exactly.
- Pickup handle
- The tolerance is hardcoded. The offsets are not relative to the weapon's axes, but to the world axes (!).
- This is a rather nasty "feature" (actually, the offsets should be relative to the weapon's orientation)
- The way it's now, the pickup volume of a WMC is not necessarily next to the handle. That's why it's hard to pick up.
