A couple of years back, I played and completed a game called Titan Attacks! on the Vita. At first it looked like a crap Space Invaders clone, but by the end I found I’d really enjoyed it.
Ultratron, by the same people and seemingly set in the same universe, does for Robotron what Titan Attacks! did for Space Invaders. A neon, chunky twin-stick shooter with purchasable power-ups and upgrades, bosses, and particles everywhere.
And, just like before, what seemed like a poor copy of an arcade game from 30+ years ago turned out to be a lot of fun. It’s a bit mindless, and the amount of pixels flying around in the form of explosions, pickups and bullets can make it a little hard to see some of the time, but I happily completed it and then carried on playing some more.
