I’ve been doing a lot of experimenting with builds recently. Been enjoying the blitzer electric shotgun for the bugs. Great chaff clear, kills anything smaller than a charger, or stun-locks it so it can’t move. Grenade pistol as you said. Usually stun grenades for charger control or keeping all the gribley inside an aoe. Depending on what my squad has either the flamethrower or anti tank. I usually end up running the anti tank so spear or recoilless. I’ve been enjoying the spear recently love the fire and forget but I do find it doesn’t reliably take down much in 1 shot unless you get it really well lined up. I always love a cluster bomb. Been enjoying the airburst and napalm for area denial/ breaches. Guard dog laser if I’m not taking a backpack.
Good for you. I hope the move goes smoothly.
