Lightning Fighters (aka Trigon)
Lightning Fighters (aka Trigon)
Is it just me, or does this game seem extremely "Raiden-ish", despite being too old to be a Raiden clone? The limited side-to-side scrolling, the powerup system (particularly the two kinds of bomb, one offensive and one defensive, closely analogous to Raiden 2 even if how each bomb type looks and works is very different), the types of enemies that appear and their movement/shot patterns, and the way the game looks and sounds are all very close to the early Raiden games.[/i]
According to the review here, there is a special hidden weapon in Trigon that isn't in Lightning Fighters. As far as I know, that's the only difference, except for the fact that you play as Vash the Stampede in Trigon.

The reason for the lack of checkpoints and the absence of the homing weapon in the US version is that the US version is always in "2 player mode". As the review notes, Trigon (and the World version of Lightning Fighters) has some rules differences between 1- and 2-player games:
1-player:
You start with no bombs
When you die, you restart at a checkpoint
The homing pod weapon appears
A second player cannot join in mid-game
2-player:
Each life starts with one defensive bomb (Lightning Sword/Plasma Beam)
When you die, you respawn in-place
The cooperatively-controlled pods appear, but only when two players are actually present
If one player runs out of lives, they can reenter at any time
The US version always uses the 2-player rules, even when you start with only one player. I think they did that so that a second player could join in mid-game (which isn't allowed in the non-US versions)
Another difference between Trigon and Lightning Fighters (both World and US) is that the blue, defensive bomb is called "Lightning Sword" in Japan and "Plasma Beam" everywhere else.
Anyway, I need to play more late-80s verts! On closer investigation, it turns out that just about all of them look and play like that. So I guess Raiden is really just a final, "perfected" expression of that sub-genre. The only vert I played in arcades much during that time period was 1943, which of course was a major oddball due to having a lifebar.
