Apart from a shotgun, the above I think is missing from the game. Something that can launch the grenades already existing including smoke and nerve gas. Would bring a whole new dynamic to the game and refresh the old missions.
Not just as a defensive measure but also for attack.
Of course Steve would have to program this; I'm a complete novice when it comes to doing this thing but fully mindful that it takes many hours to do it. But,it could bring new customers to it if a new version came out with new weapons not just cosmetic changes. Also old players might return. Of course the latter doesn't bring in money, vital for anyone trying to make a living, but word of mouth would increase. Unless you charged those already playing a reduced amount to obtain the new version also and those new ones an extra 25p on top. I would pay a couple a tenner to have shotguns and grenade launchers added. Would anyone else.
I put a couple of quid but realistically ws would have to throw in a tenner to make worth Steve's time. In addition to a new weapon version in the play store that would attract attention.
I would be interested. It would have to be a range of weapons. I would like Proximity Mines, Remote explosives, Samurai sword, shotgun, grenade launcher, AK 47 machine gun and pistol with silencer. I would be happy to pay 10 quid for that lot plus some new missions.
