This thread is to document the mortems for all the badges and medals I obtained in 0.9.9.8, as for most of them I did not feel like making individual threads here for (and so the Post Mortem board does not get flooded with my runs). This also records my progression to 100% (or rather how close I can get, given how some of the Angelic badges are currently realistically impossible). I additionally will be using a scoring system I devised to track how "close" I'm getting to 100%, which is being used instead of just doing a flat percentage of every badge/medal because it would be silly to treat a Bronze badge of equal weight to an Angelic badge. The scoring system is as follows:
*Each 
Bronze badge is worth 1 point
*Each 
Silver is worth 2 points
*Each 
Gold is worth 4 points
*Each 
Platinum is worth 8 points
*Each 
Diamond is worth 16 points
*Each 
Angelic is worth 32 points.
*Each 
Medal is worth 3 points.
While badges can vary significantly in difficulty in each tier (e.g. Brick and Lava Silver have probably been obtained less than most Golds and even some Platinums, whereas Gatekeeper Diamond is easier than most Platinums), the difficulty average of each badge tier is roughly twice as hard as the preceding tier, and doing it this way, I won't get bogged down with trying to attribute specific subjective scores to every individual badge. Then there are medals that are tricky to score, as there is no discrete tiering with them, and they range wildly in difficulty from Bronze level (Arena Bronze and Hell Arena Champion are literally the same thing) to harder than most Platinums (few people have probably ever gotten Hell Arena Pwnage or Chessmaster's Cross, and Dervis' Medallion is literally the same thing as Centurial Diamond). For simplicity sake, each medal will be assigned 3 points regardless of difficulty, so again I don't get bogged down with assigning subjective scores to every individual medal and so the maximum score ends up at a clean 1500 ((26*1)+(26*2)+(26*4)+(26*8)+(26*16)+(17*32)+(50*3)=1500)
First standard HMP run for many Bronze/Silver/Gold badges and medalsThis is my first run of the official 0.9.9.8 release (well I had one run before, but I tested an old telefragging bug that someone reported, and after it was confirmed fixed, I decided to kill myself by telefragging to see if you got a funny death message for it, unfortunately you don't :( ). The Unlock All setting was bugged in the release version, with it not unlocking the harder difficulties, so I had to start off with a standard HMP game. I did a quick run through with the currently broken Vampyre in a mostly uneventful run that gathered up many of the easy badges and medals, other than me taking a detour to obtain Iron Skull for the first time (which thankfully had its requirement reduced to a less absurd 5000 damage). Still a tedious medal, but I didn't need to spend too much time on it, as getting halfway there at City Of Skulls, and then just taking many lava baths before picking up healing items/powerups in the second half of the game was enough to get me to 5000 damage.

Here is my first official UV run of 0.9.9.8. I advanced enough as a player that I can consistently fully beat standard UV with virtually any build and don't need to make any thorough plans for it, so I just went with my favorite build of Shottyhead here. Aside from picking up some more Silvers and Golds, I reobtained Veteran and Elite Platinum here, while also picking up the Hell Arena's Key and Shambler Head (the latter of which I believe is the first time I got it outside of AoMC). Nearly picked up the Angelic Pin too, but making Nano Shrapnel with the Double Shotgun proved to be a mistake as I couldn't hit things outside my vision with it without shooting at very specific angles, so I tried waiting the center of Mortuary behind the walls for cover after clearing out one side, where an Imp then got a double move and hit me (I thought Imps couldn't do that to Scouts, but maybe wait was changed to no longer be affected by the Scout's speed bonus?).

For the official 0.9.9.8 release, I opted to not use the Unlock All option, as I wanted to see how quickly I could unlock everything. So after the UV run, I went for the quick Angel Of Pacifism run to get another rank of unlocks, which took some attempts, and in one of those failed ones I got Pacifism Bronze (excluded the mortem here because I forgot about it initially and trying to edit it back into this first post later had it hitting the character limit, while I didn't feel like editing all the posts to fit it in chronologically, surely no one cares about the mortem for a Bronze badge?). In less than an hour I was able to get a successful run, picking up the Pacifism Bronze to Gold badges, as well as all the Icarus and Compet-n crosses, which got me enough medals to get Heroic Silver too.

Next up I went for an A100 run once it was unlocked, easily my favorite challenge mode, and throughout all my time playing DRL, I have probably put as much or more time into A100 runs than I have playing standard games. Again I can make about any build work in A100 on UV (I even did a 100% UV A100 run with Entrechment once during the beta process), but went with Scavenger here. Part of it is because Scavenger is really fun in A100 (especially so with 0.9.9.8 letting Scavenger now disassemble any type of equipment), but part of it is I also wanted to build as many assemblies I can, particularly the annoying ones that require rare weapons and/or rare mods, to both build towards the Technician badges and to get them out of the Schematics pool for Armory/Deimos Lab (unfortunately 0.9.9.8 has not changed how Schematics drop, so you want to get all the assemblies done ASAP so you don't have them cost you a crucial rare mod in any of the harder challenge runs). There was still quite a few I was unable to make (quite annoying I didn't find a single BFG nor Chainsaw despite them being made less rare in 0.9.9.8), but I was able to get the majority of assemblies done, while thanks to Technicians getting the newly added WK3, I was able to build the ultimate pistol to completely eradicate the lategame (a P3N2S2 Combat Pistol, a 3d6 Combat Pistol that was effectively Nanomachic and retained its accuracy against out-of-sight enemies). With this run, I get the Centurial Bronze to Platinum badges done, as well as the Experience Medal.

0.9.9.8 added new some medals, four of which are the Pacifism Medal (win with 10% or less kills outside of AoPc), the Shotgunnery and Marksmanship Crosses (win with all your kills being with fists and shotguns or pistols respectively, outside of AoSh and AoMr), and the Zen Master's Cross (win without directly killing anything outside of AoPc). These medals are quite annoying (especially the Shotgunnery and Marksmanship Crosses that feel pointless when we already got weapon-locked challenges), but in the beta testing I discovered that going for the Zen Master's Cross will get all those medals, as well as the Malicious Knives Cross and Sunrise Iron Fist, due to a technicality in the coding where those medals are earned by not recording a kill with any disqualifying weapon. So if you don't kill anything directly... you don't record any disqualifying kills, and thus you'll obtain all of them in a pseudo-pacifist run.
With that in mind, I just did some quick AoOC runs on HNTR playing a stair-diving pacifist, nabbing the Nuclear BFG from Mortuary/Limbo, and then nuking the Mastermind. It took a few attempts, but you don't need to get that lucky to win this way. With a whopping six new medals from this run, I get enough for Heroic Gold, and also pick up Daredevil Gold too.
