An absolutely ESSENTIAL rom hack for Contra fans. EXTREMELY underrated.

Reviewed By: Light MetaS on 02 Dec 2019

This is an absolute beast of a hack.

It’s a complete and total reworking of Hard Corps. All alternate paths are combined into one singular adventure. The bosses who were underutilized in the original game are now much bigger threats. The original game had several boss attacks and attributes that the player could be totally unaware of, AND there were even some attacks that hardly did ANYTHING. It’s a shame as well, because they often were visually extremely cool, but just ended up being a waste of space. Not only do the bosses get proper time in this hack, they are also made to be harder. Way harder. Holy crap they’re hard.

There are definitely points when it seems nigh impossible to avoid damage. Players could definitely argue that it’s on the brink of unfair at times. Fortunately, you are also provided with nine lives per continue, nine continues, and best of all, not three but FOUR hitpoints per-life. From my experience, it wouldn’t be difficult to get through the game in its entirety on real hardware due to the fact that it’s entirely forgiving. My only other complaint - You do NOT want to be stuck with the basic weapon on some of these bosses. Just trust me. You’ll be waiting around for a while.

I also want to push a new release with a few bugfixes. Fun stuff, right? I encountered a few -

1. The cutscene at the start of the train level shows a glitched character. Specifically, I encountered this when using the tall blue robot from Probotector. Using the main male character erased this problem.

2. Right before the missile riding section on the stage where you fight Bahamut, as you leave the screen it begins to fade. You can quickly see him begin to arise, and his text is cut off by the transition to the aforementioned missile segment.

3. Perhaps the most important - The game crashed a couple times when I completed the second-to-last stage while using the same blue robot from Probotector. Changing to the female character fixed this.

It seems generally that the game struggles when coping with the fact that there are more than the initial four characters from the original game. This is the only roadblock in the experience.

On a side spoiler note. The ending was absolutely devastating. My jaw dropped.

Overall, it’s an absolutely amazing experience, and it’s a dream come true. I remember daydreaming about a build of Hard Corps that had these features, and I send my warmest appreciation to the talented programmer behind this monster. The creator had an absolutely fantastic vision of what the game should have been. I absolutely cannot recommend it enough to fans of the series, and specifically to veterans of the original game.
