How to unlock the Survivalist achievement in Under Siege - Definitive Guide
You can't have any units die. That means if you have a group of three archers, if even a single unit of the group dies, you won't unlock this. NOTE: It doesn't matter if friendly units die (the units with a white health bar), only units you actually control (blue bar). If a group joins you mid-battle, the only thing that matters is from that point onward (which happens after some dialogue).
Chapters 1 and 2 are the hardest, so I strongly suggest doing this on Chapter 3. Have the archers/shamans heal each other (and whatever else you have on your team). Take your time, don't rush in, and you'll be OK. See the tips posted in Hardcore and Chapter 3.
Clicking restart at the end of the map will NOT work. If a unit you control dies, QUIT via XMB, and select campaign>continue when starting back up. (credit to Bahamut for trying this and confirming it works)
WARNING: Some people had this glitch on them. The only known solution is to re-install and do it again. (credit to Nothingface17 for posting the solution)
We set the difficulty level to Casual, monitor our units and heal them (with the help of archers), as soon as necessary. The easiest way to get this trophy is by completing the first chapter.
Try to collect as much gold as possible (By collecting chests and killing enemies (For each enemy unit killed, you will receive gold coins)) to improve your troops (When you level up, soldiers receive additional health units).
The first chapter contains five missions and training. I'm not sure about training, but just in case, try to keep all your soldiers alive.
At levels 1-1 and 1-2 there will not be any special difficulties. It's the same with training.
At levels 1-3 you will be told about a gunner who is being captured by the undead. Be careful in two cases:
1) when fighting with giant worms that poison your soldiers (whose health will gradually decrease for about 3-5 seconds).
2) when using a knight gunner. In his hands is a cannon that shoots explosive cannonballs. Try to shoot where your soldiers are not, otherwise you will kill your own soldiers with your own hands. One more thing... watch the shooter's health, as he doesn't have much health.
At levels 1-4 the only challenge will be the enemy gunner, but he can be defeated with a little cunning. After the battle with the first enemy units, go to the left (2 sword soldiers are patrolling there and 3 archers are standing on a hill). After defeating your enemies, bring your gunner to the edge of the cliff, who, in turn, will have to destroy the stone blockage enclosing the giant worms (I advise you not to kill the worms, as they will kill the enemy gunner and several more enemy soldiers).
At level 1-5, place the gunner on the nearest mountain, aim at the gorge and press for constant shooting. Place the remaining soldiers (2 squads of archers and one squad of swordsmen) to guard the gunner. When the golems appear, kill the enemy “side dish” and send your archers into battle. Shoot the golems from a distance, preventing them from getting close. Repeat the same with the boss, running in circles from him)
Congratulations, the trophy is yours.
At the end with the boss, do not forget to use 1 ability on the swordsmen, so the goblin will be distracted by them for a while.
