From a technical point of view, I suppose you're right but... ok, to make things short, wouldn't be as cool if there was no pilot in the thing, I hate remote controled things, they ruin the "chivalry spirit" of the whole thing

Didn't have the time to work on it today, only added the outer side hand bump map. inner side and fingers next, then legs, then feet ( altho I may redo the meshes completly first, I'm not too happy with them ). They I'll have to work a lot on the body before bump mapping it.
I dropped the gyro arm thing for the weapons, would be an IK nightmare to do, and the setup of the mech makes it kindda difficult to execute anyway. the gun support will just be lowered when needed, the gun picked up, then the support goes back to place, it won't stay and move with the gun anymore as I planed.
For now, I've planed 3 kinds of weapons ( I want to base them on real weapons, so I'll have to decide which country this ArmS is from first ):
1) the machine gun. I'll have to look at todays very large machineguns to adapt one. The obvious choice would be the Avenger, but it's a bit cliche, and I have to check its scale first, compared to the Hulk
2) Sniper rifle: well, basically, an adapted tank main gun, with smoke and sound supressor.
3) "shotgun": I completly made up that one, and the mesh is even done already ( tho a bit on the high poly side... ). Basically, you have fast firing versions of a hand gun, well, the Volcano would be a fast firing version of a shotgun. A gatling shooting very large area projectiles if you want. Of course, the rate of fire is nowhere near the one of a gatling, something around 2 or 3 shots a second probably. The shell works like a shotgun shell, it doesn't go, instead, it's spews lots of metal marbles. The weapon is designed to supress mycoids groups at short range. Bah, to make short, it's just a cool looking, devastating big gatling

there, a pic:

I'll make the main "body" longer so it can be carried easily ( two-handed weapon ). Also, the ammunition cartridge ( the box underneath ), is really too small to be any realistic, I'll remove it, and ammos will be carried in the ArmS backpack, and fed to the gun via a chain ( same setup for all the weapons ). The current cartridge support thinguy will be used to dock the weapon to the right arm, and luckily, the two round things on it fits perfectly to the two round bits on the arms. Lucky

The weapon will be held up side down.
