A Yolona Oss fires its strategic missile

The Seraphim Experimental Missile Launcher, nicknamed Yolona Oss, is a Seraphim experimental unit.

Yolona Oss is much like the normal T3 strategic missile launcher, but the missile is much more powerful and so large that two defensive missiles are required to neutralize it. By the time the two anti-nukes even hit the nuclear missile another one can be sent on its way. The only way to defend against a Yolona Oss long enough to make a counter-attack is to have multiple anti-nukes with existing missiles around your base.

Although extremely expensive, it does not appear to have the Manual Build ability associated with it, possibly because its missiles are automatically constructed, similar to the Strategic Missile Sub's tactical missiles. Its missiles also take much less time to build than missile defenses, so if one is built victory is almost assured. It is in a similar category as the Mavor: Expensive, but essentially a game ender. The only problem with building this unit is that if you construct it, you would not have the economy to build an army to protect yourself, so your enemy could build an experimental and crush you. All around an effective unit; fast missile build rate, long build time, and economically a mass and energy drainer when being built. Compared to the UEF Mavor and Cybran Scathis the Yolona Oss costs slightly less mass (roughly 50,000) but immensely more energy. The Yolona Oss is by far the most energy-expensive unit in the game so you must have an extraordinarily well-developed power grid before you start to build one or you're guaranteed to energy crash in seconds.

Assisting the Yolona Oss with engineers may seem counter intuitive at first considering that you need 432 t1 engineers, 216 t2 engineers, or 144 t3 engineers to double its production, but it is significantly more cheaper to build these large numbers of engineers than it is to build a 2nd Yolona Oss so assisting the Yolona Oss is definitely recommended. For example, it costs 22,464 mass to build 432 t1 engineers, 34,560 mass to build 216 t2 engineers, and 70,560 mass to build 144 t3 engineers.

The Yolona Oss launcher has a maximum capacity of only a single missile, so whenever it completes one you should launch it immediately so it can begin constructing the next one. While a single Yolona Oss missile can regularly end the game in a single shot, destroying anything in a huge range and dealing impossible damage, you should never take this for granted and should launch as many missiles as you can. This will seal the victory, as 9 missiles can cover a 5x5 km map quite easily.

If launching towards a base with many SMDs, shift click the nuke a bunch of times so it automatically launches a flurry of nukes towards the base without your attention.
