After months of work our programmer had finally managed to work out under barrel grenade launchers.
As you know, GEM engine strictly forbade to have secondary weapon on a rifle. One rifle = one weapon. There were attempts to overcome this by having 2 rifles on a soldier, one firing grenade, one firing rifle ammunition.
1. select a soldier that carries AK-74 with GP-25 (another good thing is that whole operation is not linked to a soldier but to the rifle itself so any soldier can fire it)
2. select appropriate action (grenade launcher)
3. click on a place to fire there
Or you can take direct control and click right mouse button (to load the launcher) and left mouse button (to fire it). Simple and effective. And most important thing is: as soon as you fire it you can fire assault rifle ammunition, as visible here:
We also plan on some GUI enhancements to ease up exploitation of this new feature. This will surely change multiplayer a lot, no more super squads armed with RG-6. Grenadiers are now in their true form.
