*Review based on Super Earth Defense Force’s release as part of the Nintendo Switch SNES Online service*
Originally developed by Jaleco for arcades in 1991, Earth Defense Force made its way to the Super Nintendo Entertainment System the very next year, with the appropriate “Super” added to the title. Super Earth Defense Force is a simple side scrolling rail-shooter that provides competent enough fun, but features some questionable creative decisions that hold it back.
The player takes control of a space fighter, which is accompanied by two satellite fighters. At the start of each stage, players can select which weapons the satellite fighters have, with eight possible options. But you should always pick the “homing” option.
This is the game’s first big creative misstep. The homing attack is so overpowered and so much more useful than the other seven options that it makes them close to pointless. I’m not talking about the good kind of overpowered which simply makes the character feel more powerful, like the cape in Super Mario World or the Crissaegrim from Symphony of the Night. This is the bad kind of overpowered, as in “did anyone test this to properly compare these weapons?” Though the game sees the player automatically traveling to the right side of the screen, enemies don’t just spawn ahead of, but behind, above, and below as well. As such, the homing attack is the only one that can reliably hit these enemies. And in some instances (even on the first level), there are numerous enemies descending from the top of the screen that are difficult to avoid unless you destroy some of them, but you can’t hit them unless you – as you might have guessed – picked the homing attack. There’s no reason for you not to pick it.
The player has three hit points, and four total lives. The only way to heal is by completing a stage, and there is no way to gain extra lives. Additionally, the stages feature no checkpoints, so every defeat will send you back to the start of the current stage. This all makes sense for an arcade game, where no doubt additional coins would allow for more continues. But it’s a shame that Earth Defense Force’s transition to the Super NES didn’t consider the differences in arcade and console gaming. With no way to heal or continue past your four initial lives, it makes the game an entirely trial and error approach. You’ll make more and more progress every time you play and figure out which enemies spawn at which point, but only after learning from being defeated by surprise attacks time and again. That might make sense for an arcade game, but on the SNES, the occasional healing item or extra life would be appreciated.
In the case of extra lives, Super Earth Defense Force even provides an apt opportunity for such things. As you defeat enemies, you’ll gain experience points. Once your experience bar fills up completely, you’ll gain a level, which will upgrade your weapons (preferably your homing weapons). On the plus side, you’ll keep your accumulated level and experience points even after you lose a life. On the downside, this would have been a primed opportunity to also give the player an extra life, giving them more time to utilize and appreciate their upgraded weapons.
As it is, the game’s trial and error approach will see you gradually gain a level, die, then make more progress through the current stage with your upgraded weapons. With only four chances to make it through the whole game, the experience becomes little more than a memorization game.
Super Earth Defense Force isn’t a bad game. The gameplay is simple and fun, the graphics are nice, and the music is catchy enough. But Super Earth Defense Force isn’t really special in any particular way, which means it can’t really make up for its increasingly tedious sense of trial and error. Playing on Nintendo Switch makes it a bit more tolerable, given the save states provided, but such things weren’t in Jaleco’s mind when developing Super Earth Defense Force back in the day. Even the game’s attempt at variety is undone, thanks to one weapon option being as objectively right as you can get in this kind of scenario.
