Kangaroooo's Guide to All MOS

## Introduction

This is a guide for brand new players to intermediate players who want to learn how to play this game, who want to learn the game mechanism of this game, who want to improve their skills, who want to become a carry or pro, for whatever reason, either fun-based player or hard-core based player. This is not a guide for "pro", whose definition we will clarify later, due to the reasons below.

1. This guide helps to understand better about this map. At rare situations or challenging difficulties, a pro might be playing in an extremely non-instinctive way, whose skill points, SI talents, and playstyle would differ significantly from this guide. However, that also requires deep understanding of game mechanism. So understanding the basic mechanisms of this game is always a basic thing.
2. If I'm still playing this game, I should be able to know almost all the pros or good players as an officer of clan<isar>, a regular player, a discord moderator and an in-game admin. It's not possible that someone can only practice solo this game but never play in multiplayer mode and become a pro (even though solo is a very important part to practice the skill). Therefore, I would probably meet him/her in game and we can directly communicate in game/on discord. There is no need to read this wiki.
3. if I already quitted playing this game, then this guide would possibly goes wrong at some places since I'm not following the update of the game anymore. However, I do believe the statements about the things which remain unchanged (e.g. how to drop cff, call for fire) should also remain true in the longer term.

## Who wrote this?

Having been playing undead assault 3 for 4 years(not on EU server, so there might be differences) and undead assault reborn for 3.5 years, I played around 5k ua3 games and 3k uar games. There are much more players who play longer than me, who play better than me for specific MOS(Military Occupational Specialties) or who play better than me for specific game difficulties(Modes). Though there's no leaderboard in this game, I did win almost all the impossible difficulties in this game, with wonderful teammates who do their jobs. This should be noted since it's a highly cooperative game, there is no clear criterion to say who is better and who is not between two good players. While at the same time, many strategies/playstyles are only good strategies/playstyles when you are playing with wonderful players, and they become trash/bad strategies when you are not playing with good players. To prove yourself to be good teamplayer is much more important than to prove you can solo the challenging difficulties, because solo and multiplayer(12 people game) are totally different games. And more challenging difficulties will 100% need 4 people or 12 people team to win, such as nightmare T1 rifle in ua3, or in uar without the power-armor buff.

Sadly, there is no online leaderboard or any recorder for the challenging difficulty wins. If someone have doubts on my statements, I'm happy to discuss or test or play together in game. Here are some but not all modes I've won:

1. Nightmare T1 rifle 12 ppl in ua3, when I was quite new and get heavily carried by an extremely good team on CN server.
2. Survival T1 rifle 12 ppl in ua3, when I was quite new and get heavily carried by an extremely good team on CN server.
3. Nightmare T1 12ppl in ua3, using FSS, jav, cyborg, ghost, sdm, SFAAT, med, platoon leader separately.
4. Survival T1 12 ppl in ua3, using all MOS available in ua3 separately.
5. pmc T1 12 ppl in ua3, using FSS, sdm, SFAAT, cyborg, med separately.
6. solo survival T1 in ua3, using sdm, FSS, jav, cyborg, and enhanced autorifleman(enhanced means incendiary rounds and suppressive fire can be used together, since they can't be used together before some updated version) separately.
7. solo insane T1 in ua3/uar, using jav.
8. solo survival ob in ua3/uar, using all MOS available in ua3/uar separately. The only exception is combat walker in uar since I personally am not a fan of this MOS and didn't try it.
9. solo nightmare ob in uar, with the help of power-armor update, using autorifleman.
10. solo survival T1 in uar, using platoon leader, autorifleman, FSS, jav, cyborg.
11. wins of new modes(12 ppl), i.e. PMC+, Invasion, Infested.

## Links to all MOS explanation

I've soloed about 1k games in survival T1 and carried about 1k games in 12ppl Nightmare outbreak/Survival T1 in ua3, using the main carry FSS, jav, cyborg, sdm in this mode. Hence that's the MOS I'm most familiar with or good at. Sadly, cyborg and sdm has undertaken great nerf in uar comparing to ua3. I can't say I'm the best user for them in uar but they remain at the top of my best MOS. From the best to the worst, all MOS I'm good at should be ranked as following:

1. Jav. So far, I can't find another better javelin gunner.
2. FSS, cyborg. Due to huge amount of practice. Even though cyborg has been greatly nerfed with respect to damage, it remains a functional MOS. FSS has been buffed due to WK works on his abilities. Though it's hard to say I've reached the maximum usage of buffed FSS.
3. SDM. So far, I can't solo survival T1 in uar using SDM as in ua3. Might be the nerf of the MOS itself or I'm not used to the new update in uar. So I put it 1 rank lower than cyborg and FSS.
4. Alligator, Assault Engineer, AutomaticRifleman, Ghost, Combat medic. Those are MOS in uar which I've been practicing and getting familiar with or MOS that I was playing at an intermediate frequency in ua3.
5. Platoon leader, rifleman, flamethrower, prototype, calvary scout. PL and rifleman has been greatly buffed in uar due to the "correction" of critical shot system and the great buff to rifleman guns. Those are MOS I tried to practice in uar, as well as the new MOS in uar, prototype and the calvary scout who has been modified dramatically. Flamethrower hasn't been changed much, but personally I don't play very often in ua3.
6. SFAAT, combat engineer. Those are MOS which I'm good at in survival mode but hardly want to play in other challenging difficulties.
7. Reaper, Grenader, Sniper. Those are new MOS in uar which I hardly play. So there's no guide for those 3 MOS for now. If this page is updated in the future, these 3 MOS will be added.
8. Phoenix medic, combat walker. I don't play them often and only pick them when the team is good enough to carry me. So there's no guide for those two MOS.
