Some of the concepts we think of as modern inventions in gaming are anything but new. Upgrades and power-ups are two totally different approaches, and the "new" action games tend to favor upgrade systems, a la the Action/RPG. The idea of branching development streams and "tech trees" in RTS games are all components of what we like to think of as progressive game design. Some time ago, all the way back in the eighties, gamers were getting a dose of
Gradius, a side-scrolling space shooter. One of the first choices to make was the upgrade path of the ship you were flying into battle. One of several options for weapon upgrades and shield were selected before going into battle. Depending on your style of play and the territory you intended to conquer, the upgrade system allowed for personalized gaming. Sure, there was a linear upgrade system, rather than true a la carte or point-system upgrades we see in modern action titles, but the foundation for those modern games was being poured when games like
Gradius won hearts and thumbs twenty years ago.
The premise or story in the game is ridiculously simple, and hardly worth mentioning. Tackle wave after wave of enemy, fight a mini-boss and a final battle before doing it all over again. Shoot enough of the right attackers and you'll be rewarded with an upgrade pod. Collecting pods engages the upgrade system, and you can either auto-upgrade or control the weapon choice for upgrades manually. Once you get acclimated to any of the games in Gradius Collection and figure out the timing, manual upgrades are key. With these, you can select the weapon that suits your play style and gives you the greatest advantage in the area you are passing through. Strategic (read "smart") players don't rely on chance when Konami allows you to be master of your own destiny.
