In 2384, unknown invaders attack the Jupiter base and finally reach Earth.
Although the Earth Federation has prepared a counter offensive, the chances of success are very slim.
But the Asian Federation has a secret weapon, the SERD Squadron, and its mission is to find and destroy the invader’s bases and drive them out of Earth.
Hiso Kihei Serd is a turn based war game at its core and in any given mission the player must deploy and control a number of Serd giant robots on an overhead map – each mech comes with its own characteristics, some are fast and have long-range attacks whereas others are bulkier, slower but use more powerful weaponry.
When a fight between two opponents is triggered, the screen switches to an animated sequence.
Each Serd gains experience in battle which may be used to enhance its attack and evasive capabilities.
However, should one of the Serd be destroyed during a given mission, it is gone for good but more (up to seven) can be acquired as the game progresses.
Hiso Kihei Serd consists of ten missions and is single player only.
A password system also allows the player to save his progress (although the backup RAM can also be used).
It is important to remember that some units possess a special ability, many of which can easily turn the tide of the battle.
Using them wisely is a key to quick victory in later stages.
Overall, this is an enjoyable game, and a prequel to Vixen 357.
One can easily notice the similarities between these 2 games, and it’s easy to pick up one if you’ve ever played the other one at some point.
About PC Engine
Known as the TurboGrafx-16 outside Japan, the PC Engine (1987) punched well above its small form factor and was hugely successful in Japan despite a limited Western release. Because the Western TurboGrafx-16 library is comparatively small and undersold relative to the platform's technical merits, complete-in-box North American copies are notably scarcer — and pricier — than their Japanese PC Engine counterparts.
Gamevaro tracks Hisou Kihei X-Serd for PC Engine with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Hisou Kihei X-Serd to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PCE release dates back to 1990.
