Hehe, I remember explaining to Micro how I did it so he prolly used my method. Here's how to do it:
As everybody knows you respawn with a primairy and secondairy weapon. The trick is to change the slot the gun is using for a gun you don't use often. Example:
//-------------------------------------------------------------------------------------
// SKS - Simonov
//-------------------------------------------------------------------------------------
`w_new 15 2212 7963
`w_animgroup F
`w_slot 3 // <---- change for claymore ID
`w_model VvH_Simonov
`w_use 1 0 30
`w_magazine 0 3 10 2.98
`w_mag_reload 0 1.78 0
`w_ext 0.1 6 0.9 1
`w_aimswing 0 0 0 0 0 0 0
`w_hud 1 43 11 1
`w_tracer 1 174 254 7 1
`w_reload_signal 10 0.5
`w_bayonet 2.1 2.1 0.5 0.6
Now you can pick up a dropped SKS - Simonov and bayonet with it. Not shooting (yet), therefor you have to do some memory editing. Step one is done, now go and try to edit some memory to get it fully working.
I tried a differend method on Vietcong 2 and got it fully working as well. Respawning with 2 sniper-rifles, an AK47 and M16, 2 pistols, a machinegun, 2 knifes, a radio, medkit and ammokit.
