I've been pondering buying a Stream Deck for macro button use for games but putting it off for over a year. I got notice of an upgrade for a HCS Voice Profile Pack I bought for Elite Dangerous a few years ago, which gives you voice control macros and responses instead of pushing one of ~85 different buttons (lower landing gear, power to weapons, etc). This got me thinking about using Voice Attack, the software that powers the HCS Profile pack. Then I found a Voice Attack Profile for Helldivers 2 on Nexus Mods, and now I can use voice commands to call down reinforcements, stratagems, resupply beacons, etc. instead of using the sometimes long arrow button combos.
TLDR: Voice Attack will make my already fun Helldivers 2 game time more fun.
