The One Probe is a unique mod that comes from the Minecraft mod. This mod gives players the ability to build and place one probe at any position on the map. Players can then research this new technology at a Research center. The One Probe can be researched at a Mining Station, and it can also be built at a Surgery station. There are two types of One Probe recipes, which include having two mining modes, and having three mining modes.
The One Probe is an excellent unit for building defense against air attack units, such as the Medivac. The One Probe can be upgraded into an Overlord by using the Research abilities. In that way, the player can have more Probes than the enemy. When in a battle, the upgraded Overlords can hover over enemy units, and then attack with their fully equipped Heavy Attack mode. The mining mode can also be very useful, as it can mine minerals and other resources while being scanned or without being mined at all.
The One Probe is similar to the Baneling in that it is only weak to air attack units. The One Probe has an economic advantage over the standard Baneling, so it is generally used for early game mineral gathering. When the opponent sends early Marines, Marauders or Medivacs, the One Probe is very useful for scouting. The probe can also do ground attack damage, although it lacks the speed of its faster counterparts. The One Probe is similar to the Baneling in that it is only weak to air attack units.
The One Probe can be upgraded into a Spider or Webite. The Spider can use its speed to get around the map quickly and effectively, while the Webite increases the damage of the attack units the same way that the Overlord does. The One Probe can produce these units at a rate of roughly one per minute. It is unknown if they are more efficient at repairing the structures or not.
The One Probe is very useful for building up the economy as early as the game, but it is important to note that these units are quite weak early on. The Photovoltaic upgrade increases their repair speed and enables them to better defend themselves from attacks. However, these units are vulnerable to attacks from Zealots, especially if you cannot afford a Command Centre or cannon/orbital boosting your army. The Zealots often use Zealot charge to pierce through your units.
The One Probe is the perfect unit for harassing the opponent’s economy and allowing you to expand faster. The one probe will not be the most efficient unit in a big fight, but if you simply want to go out and make constant units, it can be useful to get one probe and keep producing units. The One Probe is also good for scouting, so you can gather up minerals at your mineral line instead of having to mine them yourself. The One Probe is one of the few builds that can survive in the late game with minimal harass.
