I had that happen too. It wasn't intentional but a weapon overheating from too much use could be interesting.
It might be running out of ammo because everything is in a WHILE instead of WHILE_EXEC and there are lots of DELAY_HERE commands. Some of that is necessary for the walking animation to be displayed.
The unlimited ammo was just for fun. I will adjust everything so you only have sensible weapons and you only get a limited amount of electrogun/rocket launcher each time you respawn. The robots need to be stronger.
That "thing" with flamethrower looks like mechs from MeshCommander 2.
What is this? New ped / player remap?
When did JernejL replaced the GFX? Long time ago or it's his recent work?
It's a replacement for the gunjeep. JernejL made it years ago but the map he used it on wasn't stable.
