Roaches are forceful Zerg units that can be obtained real early in game. They are heavily armored ranged units that be able to only attack ground. It can have ~ing very hard taking them out if you do not have the in accordance with duty units.
Mixing them with Mutalisks, Zerglings, or Hydralisks are remarkably good combos in battle. Early in the game it is best to have some Zerglings if your opponent has units that bestow well against Roaches as I be pleased get into their unit counters in a petty bit.
They can burrow which not sole hides them when planning to ambush your opponents throng but to quickly heal them up. All Zerg players should learn in what manner to micro them well to travel them most effective. Roaches have 4 extent making them very good against greatest in quantity ground units especially melee units like Zealots and Zerglings.
Upgrades
Tunneling Claws - This allows Roaches to incense while burrowed. This is a actual good upgrade to get to artifice your opponent especially if you be able to get by their units for handicraftsman harassment and they do not wish detectors to spot them. A high strategy is to ambush Terran Siege Tanks which time in Siege Mode to take them abroad rather than attacking head on that is dangerous.
Glial Reconstruction - This is not a exceedingly common upgrade players will use excepting it does make Roaches move faster. If you discover yourself going heavy Roaches then I would dispose this and spread the creep well to your opponents base to build them move fast enough to kite their units.

Against Terran
Roaches are the beyond all others answer for Hellion harassment. Terran players god of ~ going for Hellions against Zerg as they can be so devastating for Banelings and Zerglings because of to what extent fast they are. Against the 3 Barracks erect I would be careful and be associated with them up with Zerglings since Marauders are convenient against Roaches but do poorly contrary to Zerglings. Vise versa with Roaches. Roaches are majestic against Terran Thors and Marines which is common to see when you tech to Banelings and Mutalisks. The Tunneling Claws can be so useful when they commit to memory Siege Tanks with no detectors.
Against Protoss
At the away chance your Protoss opponent will journey mostly Zealots then Roaches are the most excellent units to get against them. But to counter-poise Blink Stalkers Roaches alone can have existence difficult which is why you should mingle them with Zerglings. Same thing towards if they go Immortals. If they doings Immortals then tech right away to both Hydralisks or Mutalisks while massing Zerglings to purchase time. Mutalisks are your best lay since they can easily switch to Colossi that do so well against Roach/Hydra.
Against Zerg
The best units to get against Zerglings and Banelings are massing Roaches indeed. When facing one more Zerg player you just need to watch thoroughly for air units which are Mutalisks and Brood Lords. But other than that Roaches are immense in this matchup.
