Of course, I must point out that there’s absolutely nothing wrong with Infinium Strike. It’s competently made, it never made me feel like the gameplay mechanics treated me unfairly and the rules of the game were always clear to me...just like any good tower defence game.
In it, a variety of foes approach and attack a point you deem to be important and you stop them before they can break it...again, this is just like any other good tower defence game. I do hate to compare games, really I do, honest! But it’s so difficult when a game is such a good example of a figurative arithmetic mean of a genre, Infinium Strike is simply your run-of-the-mill, dependable tower defence game.
Infinium Strike, however, technically does have a sort of unique mechanic that goes in its favour; rather than a path your enemies walk down, or a blank field with a path you form from your towers, guiding the enemies, your ship has four sides, each side will be attacked with different types of enemy, at different times, unfortunately eventually all 4 sides will be attacked by all types of enemy, so the dominant strategy is just to protect each side against all comers, as best as possible. I call this mechanic “sort of unique”, because I’ve played a lot of Plants Versus Zombies, and that’s literally defending five lanes from a variety of different enemy types that spawn in at different times but will eventually come down all available lanes, meaning that you need to defend each and every point of entry from all enemy types. Though of course, Plants Versus Zombies has considerably more levels, and each batch of levels requires a different strategy as new enemies are introduced.
