Oh hell yeah, speaking of Ponkotsu Tank.

Namco's
Assault, previously
in best shape via the superb Namco Museum Vol.4 (PS1) version, gets an ACA release, out now
in Japan for PS4/NSW (should be up
in NA/EU stores soon). Seems like it's just the OG Assault (NMv4 ported both it and its next-year upgrade kit Assault Plus) - but tbh, that's plenty. This is a behemoth of topdown tanking, one of the most distinctive yet utterly hardcore ever. There is an Early and Later version, but AFAIK it's a simple bugfix RE the timer bonus; still, nice to have.
GET ON THE READY LINE!
GET HOT GOD DAMMIT
Control config is simple yet effective, as to be expected of Hamster. There's Type A, the arcade-accurate scheme with each tread occupying a stick, as well as the pad and face buttons if you prefer, and wheelie/roll executed via pulling the sticks apart, or moving them unidirectionally, respectively. Good autofire options too.
There's also a Type B which uses more conventional point-n-go movement, with a [wheelie/roll] button held
in conjunction with [down] or [left/right] to execute. Very reminiscent of their excellent Ikari & co LS-30 configs. As there, I suggest sticking with the AC style; there's a learning curve, but it'll pay off with smoother integration of the vital wheelie and roll commands.
In truth, the tactical disadvantage of the simpler controls is far less stark than
in SNK's games, with their brutal loss of precision stationary sniping. However, there's also a decided aesthetic charm I think is worth chasing a little, even if you ultimately go with Type B; maneuvers like slamming down from the devastating but lethally immobile wheelie by rushing the sticks back together, or hauling them laterally for an emergency roll, or cranking up and down while hosing crowds (

), have a tactile, physical sense that's rare
in games of any sort, let alone pixel-perfectly hardcore STGs. With muscle memory established, it's a rewardingly smooth experience, the sticks and triggers working
in seamless concert.
TANK CONTROLS AND YOU 
Enemies are subtly dozier than your average topdown opposition, a little slower to attack. It's a concession to the control scheme that I'd say pays off richly. There's a much greater emphasis on piloting a heavy machine here, compared other subgenre leaders like the lightning-quick Granada, or even SNK's relatively conservative TANK; your enemies likewise have to move a bit more deliberately than the topdown shooting norm. While maneuverable foes certainly exist, most rely on their all-too-easily disorientating 360' threat to box players
in, with just a couple of overlapping attacks enough to put you on the back foot. The 3:4 aspect and below-center placement of your tank would've likely proven irritating
in a less considerately-designed game; here it feels just right, with your six a notable blind spot demanding vigilance, but deft piloting making evasion and counterattack a relative breeze.
The most commonly-seen enemy bullets being destructible is another smart concession, here; with enough skill and guts, you can blast straight through some pretty nasty flak, though doing so at the cost of situational awareness remains quickly lethal. Outflanking is an uncommonly powerful tack here; with the tricky lateral movement, it's all too easy to get overwhelmed head-on; learning to swerve aggressively out of enemy fire-zones and into their open sides is key.
The "trampoline" launcher panels' being globally limited to three uses per stage is an excellent touch. They're a fascinating mechanic
in themselves, with their gifting a fleeting bird's eye view of the current stage,
in addition to letting you nuke tricky spots well
in advance of arrival; treating them as preciously scarce "bombs" was absolutely the right call.
As with ACA Libble Rabble, being able to use the face buttons as the right tread should make wiring up a custom 2x four-way rig a snap for hobbyists.
After the classily SFX-only opening stage (feel that rumble!), beefeh sound a double-must for stage 3. Shinji Hosoe's war drums and keening guitars are apocalyptic. Gentlemanly restrained
in Spirit/Saber,
busted all over the shop for Assault.
