I did try dropin battles in Napoleon and they were pretty cool, but i havent had a chance to try them out in Shogun 2 yet.
You can tick a box when creating a new campaign that makes the game search for a drop-in battle from a different player continously but i think there is a bug in the system because i havent been invited to join a drop-in battle yet during the sp campaign, and i cant seem to find one either through the matchmaking system. Either a bug, or people are too scared to try it because they already are struggling against the AI.
Especially on Legendary mode is not a place where i would want to invite another player since that only comes with one quicksave each time you fight and when the fight is finished, or with beginning new turns.
In other news, last night i had the most heroic victory i have ever had, in ANY TW game EVER.
It was an online battle vs another player. I brought 4 yari ashigaru units, 2 of them veterans, 4 archer units, 1 of them a veteran, 2 loansword ashigaru and 2 katana samurai, 1 of the samurai units being a veteran, and finally 4 yari cavalry units, of which 2 were veteran soldiers.
He brought just 2 yari ashigaru to protect both of his flanks, while the main body of his army consisted of loansword ashigaru with a few katana samurai in between and a No-Dachi samurai unit in the middle, while he had 4 bow samurai units in front of his army.
Since sword units outclass spear units, and he had more soldires than i had, i was up **** creek.
A direct assault would be suicide and most of my troops would have died before even reaching the enemy, and if they did manage to get there they would have died very quickly.
Not only had he superior troops and numbers, he was also camping the high ground, which made me fight uphill which further increased the odds against me.
So instead of fighting a head-on battle, i decided to try and kill his general before rushing in my troops, with the katana sumarai up front.
At this point, looking at my army, i am sure he was completely convinced of his victory as he had the upper hand. He occupied a hill, so i had to fight up. And his troops were superior to mine, and also outnumbering my forces. I think he decided to take it easy and lay back as i smashed my troops against his battleline.
Well, i wasnt going to let that happen without a proper fight.
So, i put my veteran cav on my left flank and hid them in the forest, while i put my inexperienced cav on the right flank.
The forest on my left flank ran all away across the battlefield and around his army, though his army was camped right next to the treeline so i would have to hurry there. I would distract him with my cavalry on the right and my main army i would park right in front of his army so my archers could skirmish with his.
After a while my main army was closing, so i decided to put some further pressure on him by moving my two cav units on the far right flank of his army to try and draw some troops to that side, hoping to open his left flank for my veteran cav.
Well, that kind of worked because he moved all of his hidden cavalry units toward them, though his yari ashigaru didnt budge. A fierce melee ensued and i managed to kill off two of the three cav units, while the third was pretty battered (i guess the result of my wedge formation against his regular formation on the initial charge).
While that was happening, i moved my main army into skirmishing range, so he was occupied on two fronts. Neither of our melee troops moved.
Meanwhile my veteran cav managed to get behind his yari infantry on the left flank and skirting them very closely, but they didnt get caught so i immediately charged his general in the centre of his army before that would happen.
In the resulting fight i killed his General. When that happened, some of his archers were already fairly decimated while mine were pretty intact (i had them in a loose formation while his werent), and they were starting to panic. When is general died and my melee infantry moving in fast to kill them off, they started to rout. Which caused more bow units to rout.
After finishing off the general i quickly charged my veteran cav downhill and into a group of loansword ashigaru. Which then caused several loan sword ashigaru to rout, and before i even knew it his ENTIRE army ran away without even trying to fight! It was the biggest chain reaction i have ever seen.
My melee forces werent even that close to come into contact, but the sight of my samurai charging up hill must have scared the bejesus out of them after losing their general. Result: HEROIC VICTORY!
Hell, it happened at 3 in the night. Right now it's 13:00 and i'm STILL excited about my victory there
