This might inspire you:<br/>List of weapons on Wikipedia (http://en.wikipedia.org/wiki/Lists_of_weapons)<br/>Quite a lot of guns under 'List of Firearms by type'. You say you want a big gun, so I'd say either machine gun, grenade launcher or flamethrower. For futuristic designs, look at the ones with recent 'Year'. If you want an image and the entry on wikipedia doesn't have one, try googling the name of the weapon - That usually wields results. (Save for flamethrowers, banned by geneva convention...that's were you'd need to get creative).<br/>I guess we need to up our weaponry anyway for the consecutive missions, so it's probably overkill to take a Vulcan (http://en.wikipedia.org/wiki/M61_Vulcan)<br/>If you have questions regarding your choice, ask, I'll try to help.<br/><br/>Also, if you want the argument with Pjotr, the engine is running, key is in the ignition.. you know what to do.  ;)<br/><br/>
