Testing Game Speeds with [difficulty].
Game speed options change with the expansions. Man this makes my head spin. On Terans you can go to slower - on the others you cannot.
Wings of Liberty
- [Casual] slower, slow, normal, fast, faster
- [Normal] Slower, slow, normal, fast, faster
- [Hard] fast, faster
- [Brutal] no option – assume faster
Heart of the Swarm / Legacy of the Void/W.o.Oblivion
- [Casual] slow, normal, fast, faster
- [Normal] slow, normal, fast, faster
- [Hard] fast, faster
- [Brutal] no option – assume faster
Legacy of the Void - Main Story/Epilog – Nova
- [Casual] slow, normal, fast, faster
- [Normal] normal, fast, faster
- [Hard] fast, faster
- [Brutal] no option – assume faster
TL/DR @Kyrie Starting with Legacy of the Void Main Story slow mode is no longer available. Slower mode only for the Terran missions. Slow for Heart of the Swarm – This is not really intuitive and caused me some headache.
