Alpha 11
Ok so as has already been noted the convoy on this level misbehaves on master, presumably due to the formation speed limiting being removed, what follows is a sequence of screen shots illustrating the correct behaviour for the convoy as designed by pumpkin in v1.10 if they are left alone.
As you will see all units should move at the speed of the slowest unit and all members of the convoy should stay together as a single group. To achieve this the convoy should pause at certain points along the way to allow the convoy to regroup
The first regroup point is at the end of the first section in screen shot 5,
The second regroup point is outside the scav base in screen shot 7
The third regroup point is at the bottom of the ramp round the back of the Plateau in screen shot 9
At which point the convoy will drive up to there LZ however unlike master the player wont be given an automatic mission failed instead the artefact carrier will drop the artefact which will then be picked up moments later by the lancer unit as you will see in screen shots 10 and 11
They will then wait for there transport, the appearance of which appears to be triggered by the player, as you will see in screen shot 12 and 13, the trigger point seems to be in the same location regardless of whither you go round the back or round the front however just to be sure it was player triggered I tried siting and waiting but I got the game over screen due to running out of time and didn't see any transport, so it's definitely appears to be triggered by the player
The one caveat to this is that it only happens if the convoy has already reached the LZ.
What happens then is that the unit carrying the artefact gets in the transport the player gets the message that the enemy is escaping and then once the transport has left the map the player gets the game over screen as you will see in these screen shots
what i have noticed about the pick up is that it seems a little inconsistent on v1.10 in so much as i know that the unit carrying the artefact is this unit
however we can see in this screen shot that the drop ship picked up the wrong unit
so technically the player shouldn't actually get a mission failed there because the artefact should in theory be recoverable still, so that's something else you are going to want to look at as well because i noticed the same thing happening on master.
With regards to the building of the lancer turrets there should be 6 of them and they should be built right away and should be finished within the first 6 minutes as you will see in this screen.
With regards to the behaviour of the convoy when they come under attack, you will see in this screen shot that the unit which is actually carrying the artefact will try to escape while the escorts stay behind and engage your units.
In this screen shot we see what happens when the unit carrying the artefact is destroyed, another member of the convoy picks up the artefact, and again the unit carrying the artefact tries to escape while the rest of the convoy engages my units.
Also i checked the timer for when the convoy starts moving on v1.10 I started alpha 11 at 29:35 and they started moving at 27:45 so if my math is correct then that should equal about 2:30 minuets after you land, give or take a few seconds.
As for the victory conditions that was collect the artefact kill all there units and there return to the LZ
few well i think that just about covers things for this level, if you want my save for this level to verify my findings just ask.
