1) Can grenade launchers kill enemies in a reasonable amount of time? The GL-06 in the gameplay videos went from being an insta-kill weapon to only knocking people down, so how many grenades would it take to kill....a medium with a health buff? Having to reload more than 4 times to kill someone with it will probably be a death sentence.
2) Will direct impacts using grenade launchers be an instant incapitate, or will they just fly through character models and/or bounce off?
3) Can engineers buff grenade launchers to give them the special ammo effects (incendiary, armor-piercing)??
4) Do grenades/grenade launchers knock people down per hit, or is there a limit to how fast someone can be knocked down? Bad wording, but let me give an example: You fire your automatic grenade launcher at an enemy medic to keep him from reaching his teammate. Because the grenades knock him down each time he is hit, you can keep him on his face aka stunlock him. <---- Do grenades work like this??
