Upon starting Space Invaders Infinity Gene's campaign, one is met with the following quote from Charles Darwin:
"It
is not the strongest of the species that survives, nor the most
intelligent that survives. It is the one that is the most adaptable to
change."
Strong
words. Words that say a lot about the state of Space Invaders over the
past few years and its efforts to stay relevant. It's many evolutions
have, for the most part, always remained small and inconsequential to
the core gameplay. Space Invaders Infinity Gene, however, the latest in
the popular space shooter series, sees one of the more drastic yet all
the while small shifts in the series yet: the move to bullet-hell
territory. A definite change from the usual systematic approach of alien
dispatch. By disposing its previously methodical nature, Infinity Gene
creates a more thrilling experience where quick reflexes triumph over
strategy, unlike its predecessors. Along with this, Infinity Gene brings
with it a megaton of content to blast through, which lends it not only a
strong lasting value but the title of one of the better incarnations of
the series in a long time, as well.
The
theme of Space Invaders Infinity Gene is evolution. In this case, the
evolutionary process of moving from a methodical column-shooter into
pure bullet-hell chaos. It begins with an arcade-perfect port of the
original Space Invaders that, unfortunately, lasts for all of five
seconds before it whisks you away to the game proper. Once passed,
you're moved to a construct similar to that of 2008's Space Invaders
Extreme in that you're faced with the same columns of invaders but with
foes of varying sizes mixed in. The entirety of the first level, which
is split into six smaller stages (as are the rest of the levels), sticks
to that basic approach. The only evolutions that occur at first are the
unlocking of additional types of ships and the amount of lives you
start off with. (Unlocks occur every time the Evolution Gauge is filled
at the end of each level, which is done by scoring well as points feed
gauge's progress.) It's not until the second level that the first real
significant evolution is made: full freedom of movement.
Once
you get there, things start to change drastically. No more are you just
eliminating columns of foes one at a time; instead, you're fighting off
nearly endless waves of invaders that enter the ring from every side
and angle imaginable, typically at blistering speeds. Everything moves
fast -- so much so, in fact, that you often don't get any time to react
to the sudden entrance of foes. By the time you notice their presence,
you'll have likely already been destroyed. Its frustrating at first due
to how cheap of a tactic that appears to be, but it's key aspect of the
experience. A bit of trial-and-error may annoy at first, but once you
begin anticipating your enemies movements and spawn points and begin
using that info to your advantage to rack up points en masse, the
brilliance of the game's design starts to set in. Weaving through
legions of foes and bullets with ease is an art in and of itself. The
skill necessary to pull off flawless runs of levels is demanding, but
hugely satisfying once you ascertain the correct means of doing so. This
isn't anything new for the genre, sure (a bit ironic for a game
centered around evolution), but it still works wonders, which is more
than enough for this style of game.

A major departure from the standard isometric view that the game uses almost exclusively up until then, the change repositions the view behind the ship itself to give you a better view of what's directly ahead and generally disorient you. Adjusting yourself to moving about in a three-dimensional space here is far from easy; discerning where it is you can move in the foreground, sure -- your ship is practically pressed against the TV screen when in the foreground -- but in the background? Not so much. Distance is the primary obstacle; judging how far enemies are from your vessel is challenging due to you not having as clear a picture as you do with the isometric view. Moving behind foes off in the distance is especially challenging since they obscure your view your ship. It presents an interesting and welcome challenge. It's also the biggest evolution here. Unfortunately, segments where the 3D side comes into play are sorely underused and only appear during a couple of levels. All that's left then is seeing enemies and environmental elements rendered in 3D. That's all fine and dandy, but it's not quite as significant or noteworthy.
Apart from the mechanics, your weaponry is also affected by evolution. You begin with a standard double-barrel cannon as your weapon: A serviceable means of alien dispatch during the first set of stages, but a quickly defunct method as the intensity of the action grows. To better combat the onslaught of invaders, newer weaponry regularly becomes available, presenting you with myriad options of firepower. From a ship that fires an expanding wave of energy to one that instantly locks-on to foes both in front and behind you and pummels them with lasers to one accompanied by attack drones for added firepower, Infinity Gene has options aplenty. Each ship has its own style of play, which not only encourages experimentation to find the right ship for you, but also provides a nice bevy of ways to challenge yourself on previously conquered levels.

In terms of content, Infinity Gene is vast, containing 140 plus levels in all. A lot of content to preoccupy yourself with, certainly, especially with the added competitive aspect of leaderboards -- and that's not even counting the game's music mode. One of the more singular features of Infinity Gene, music mode allows you to create new levels using tracks of music stored on your console's hard drive, thus providing a near limitless amount of content. That's quite a steal given the game's $10 asking price.
For a bullet-hell shooter on the cheap, Space Invaders Infinity Gene is easily a bargain. Its new take on the series formula is welcome and gives a nice refreshing change from the methodical gameplay of its predecessors. And with so much content available it's certain to keep you preoccupied for many months to come. For only $10, this game is an absolute steal for bullet-hell fans and Space Invaders enthusiasts alike.
