The holodome is really great for a few reasons.
It gives you a throw back of the early bosses without them being at a really low level, and you don’t have to re-find them.
gives you unique dialogue about some BR2 charterers.
helps you level up in a fun way.
The only problem I had was the huge hole in the middle of the mad is really annoying, I got pushed into once.
Good luck to any one reading this to beat the holodome 
I still don’t care much for the holodome (including the badass round).
Specifically it’s the boring music (music is very poor in general in TPPS compared to BL2), the thing is still way too big, and the enemy variety is poor. It would’ve been much better if the badass round ended with a random boss pick, but no, we only get Flameknuckle as far as I’m aware. (On a side note: why aren’t there any places to digistruct chests like in certain areas in BL2?)
What dissapoints me the most is that by this time in BL2’s DLC cycle we had 2 campaign DLCs and a new character. So far we have a new character and a lame slaughterdome. I know there’s supposedly some huge DLC coming but having some endgame to play during the holidays would’ve been better. The holodome had the potential to be great endgame. However, apart from the Plunkett, Nukem, and T4S-R it just ends up disappointing.
I rather they take their time making a great DLC than rushing something half-assed for the sake of “endgame”.
After playing the Holodome, I can honestly say I was SO DISAPOINTED! 95% of it is recycled, even the music? I’m sorry Gearbox, but if the CUSTOM maps on Borderlands Classic have less recycled content than people who get paid to do them, something is seriously wrong here. I was really hoping for The Holodome Onslaught to be the moment tps finally shines through but I have high expectations I guess.
-Cut dome size by 1/3rd
-make all jump pads always overcharged (this annoyed me, badly)
-Add a better mission giver than another flippin claptrap (shock drop trainer anyone?)
-half the amount of gawdamn flying enemys
-Double the enemy count
-Make the round more varied (soldiers, then guardians, then seras, then ophas… Yawn)
-Make Axton less brain-dead
Then I would have no complaints
EDIT: TAKE OUT THE FKING HOLE IN THE MIDDLE OF THE DOME. Nothing worse than slogging though a boring ass half hour round just to go buttslam a guy and kill yourself in the hole
The first few rounds were pretty bad, but whatever. The bad ass round is tough though, I’m at 57 right now and I’m going to wait till I’m 60 and get some good gear before I try it again, could not complete wave 1! I was pretty skeptical about the dome until I tried the BA round, it’s good stuff. Do you get chests during the BA round like in round 5? Also I like the pit in the middle, when I was low in ammo I could slam the ophas into the pit, it was nice!
Ophas aren’t very smart. It’s pretty easy to get them to just walk into the pit, especially the spinning-blade-ring part.
People of Elpis! This is why I love Oz Kits that give Air Control bonuses. Nøpe signing off \o
On-topic:
I was really intimidated before I started playing. Since I’m on Linux, I got the DLC on the 22nd (WINK WINK ASPYR, WINK F-ING WINK), and really thought I was gonna have a bad-to-mediocre time playing it, but I actually really loved the Holodome. Of course there are many problems with it. For starters, it’s too huge to be actually action-packed enough to feel like a SLAUGHTER dome, and I’m not even gonna get on the subject of the soundtrack being just a copypasta of Eleseer, but on the good side, I never really felt like it was hide-and-seek, enemies were almost always targeting and trying to kill me, and I liked that. The additional tasks are also good, though they could have gone more creative on that matter. The weapons… I don’t really use any of them, but I like some of the concepts. But the heads and skins… [NERDGASMS]
Holodome could’ve been awesome, but it looks like they made it in hurry, according to post on gearbox about guns. WHY? There’s no reason to do something in hurry, you could’ve just said “Holodome will be delayed, because we want to add awesome things”. Nooo…Holodome is worth 6$: 5 - lvl cap, skills etc., 1 - new guns.
Spend moonstones in the bar to regen some ammo for round 5. All is going well and I decide to install the vault keys that I picked up. Install said keys and immediately get sucked into the light. DEAD! 
To be fair, the game told you to stay away from the light
…which isn’t very useful when the light has its own gravity.
You mean the warning as it is happening? haha
And it doesn’t help that said gravity effects jumping to a horrifyingly deadly amount as well, so we, who we are taught throughout the game and the Holodome itself to jump as often as we can, intinctively jump to our deaths 
I finished the Badass Round for the first time and got a Cry Baby. WTF?
The badass round gives you any of the holodome loot in its loot pool, its random within that loot pool.
So I got a T4S-R, a skin I don’t want, a Chronicler Mod, a Party Line, another Party Line, and a Cry Baby respectively.
That sucked.
Did anybody feel that Holodome Badass Round is a lot tougher now?
I do and I can see now how shield recharge bug was helping me to complete the later waves without a problem.
Shhh!
(padding for ten characters)
Got 2 legendary berrigans in total and lots of plunketts and party lines. Barely ever got a classmod above blue.
@akdere1:
The shield recharge bug is gone? I can play my roid shield builds again? Ooh, what joy.Now they just need to fix the ffyl cryo bug and then we can finally experience the dome the way it was intended.
