As we know, Blast Network/BN is the dying older brother of the raging Lockdown. Despite my suggestion may not pump more cash in, but may entertain regular BN players and drag along new ones.

This will be updated regularly, so these are not the final product of this thread.

Hallowed grounds:

Similar to a room in LoA, with respawning Bombies and Kats this lv is similar. But there are gates which will allow it to open, releasing them into the field, and there are only bombies who have no bullets or dmg, but cause heavy stun. This could cause pandamonium to help or hinder you.

Atom:

A Variation of Cross which can sometimes drop Bombs(RT/Tordy/Mortas) that stun. There are also Explosive boxes scattered and crates that release shadow fire for a short time and deals either FIRE. Has the theme of IMF.

Atom 2:

Removes fire Shadow fire crates. Replaces them with poison variant and grates hidden in explosive crates.

Atom 3:

A rare occurance, fuses the other variants in its design.

When struck by a status caused by your mishaps, it counts as a self kill. If you cause the status death, you gain a point. same with hazards.

Gel Grounds:

A Rockets replaced with Jelly Spikes which stun

Frozen:

Set out similarly to Spikes, but has freeze pits instead. Has a Colling chamber type of background.

Guantlet.

A fusion between Stone cross, Spikes and Rockets.

Here are some ideas from other forumers:

Aplauses
Mirror
> The unique place that can repel bomb back to you or to other direction(only if the bomb hit the mirror). Of course there will be some gate that prevent the bomb from hitting the mirror. To open the gate, you need to spamming the switch button. Besides, the map will be different like a Backdoor map. The enviroment will be like a Lockdown stage, Stadium

Doctorspacebar
REGAL: RJP-Themed. In the center and corners are Lumbers, surrounded by cages, that will hit targets and cause Stun (but no damage). Piles of Jelly scattered throughout the area slow the fuses of bombs that are laid inside them; such bombs can still be blown up instantly by another bomb.

DARK: Fog of War! You can see all bombs, but you can't see players and blocks that aren't in your five-square range of vision. There are a fair amount of indestructible blocks to mess with you, so check before you bomb!

COMPACTOR: Remember Bomberman's famous Sudden Death, where blocks fell and crushed you? This area has crushers going up and down in a spiral around the arena in an attempt to emulate this. When the Crusher gets to the center, two crushers appear in each corner that go through the complete spiral... then three... then four.... increasing in severity up until the end! Hit by a Crusher? You'll lose two hearts and be stuck in that spot. Crushers will also destroy bombs and stifle their explosion, and act as blockers against explosions. Be aware of the health powerups!

INFERNO: FSC-Themed, with two Spiked Wheels firing vertically down NEAR the middle in opposite directions; they deal small amounts of damage, but if you're not careful they might kill you, causing a self kill; they also cause Bombs to explode. You'll notice Sprite Circles on the vertical edges and a Lost Sprite in the middle, surrounded by respawning Stone Blocks. Take the Sprite to the circle to restore it; it'll give a Nature's Shield buff that makes you invincible for eight seconds, much like the Bomberman Safety Vest. The Lost Sprite will reappear in thirty seconds.

Set and Primed:

Random, already-set bombs are strew across the map, but will only detonate when hit with another bomb (pre-set or player-dropped). They'd most likely be set to create chain reactions, and would probably respawn.
