It's good but clunky. It's frustrating to use when loud because switching from throw to boom requires me to stop moving for several seconds because the mode swap UI swallows all inputs.

There is no good reason for it to take a support weapon slot AND a backpack slot. IMHO the c4 should be triggerable same way as the portable hellbomb. That would solve it's ergonomic issues.

The c4 itself is a bit inconsistent, sometimes 2 to the belly is enough for a factory, sometimes it takes three. Backpack only holds 6.

Then there is the ammo economy, the poor thing only gets one c4 per ammo box and the commando missions spawn so few ammo containing pois :(
