This proves that the Vindicator has a bit more recoil than you would originally think https://www.twitch.tv/noobmister/v/62764150 (Sorry for it being a Twitch link. Been having problems with getting VODs to export to YouTube lately)
This pretty much sums up the whole situation: Gunner: "Vindicator cannon ready... FIRE!" Driver:"Wait, I haven't put the stabilisers on yet!" Gunner:" OH FU-!" *flies backwards into wall and blows up* The only problem with FaceRig is that it lags a lot, so you sadly have to turn face tracking off, and even then the lip syncing struggles to keep up :S
I pointed out the knock back effect a while back in a post, it's fun to use and I saw a couple groups abusin... ehm... testing it out on the fortress map a few times a while back on the live servers. To activate that particular bug, you must be pressing any directional key at 99.9% of the charge up rate before firing the cannon. It takes practice to understand and use but it's a fun bug. Useless to say the least unless you have a person using a repair kit on your team but fun nonetheless.
Oh, so that's how it happened. From the footage I had, I thought the Vindicator had hit itself with its own shot, which caused it to propel itself backwards. I've also noticed a (less fun) bug where the Vindicator gets stuck trying to go up the ramp of the main bridge, which is really annoying when you're trying to get close enough to get a decent shot off
This happened to me on chaos side and all I could do was laugh and wish I could have been facing the other way to see if I could ram right through the gate door and straight over a team of space marines at the door.
