So I felt like updating on this game because it's totally become something special in my mind over the past bit of time.
A few weeks up the developers released a stand alone update called Strike Suit Infinity. It's something like $6 - $7, but at it's release it was half price for owners of the previous game and is on sale again. It takes the core gameplay of the original game and turns it into something like a horde mode without any real story. It's advertised as an arcade score attack game and it works really well. There are 18 rounds split into 4-6 waves. Waves are groups of enemy ships typically dominated by a particular kind of enemies, although they get more mixed in later missions and larger enemies always come with some sort of smaller escort. The real hook (for me) is that you earn credits for either killing larger ships, killing bonus ships in the shapes of transports and freighters, simply completing a round, or saving friendlies that might be around. In between missions you spend these credits to buy more friendlies for the next mission, including capital ships so you have some control over how the next battle will be shaped. I've only made it to round 14 (+/- 1), but the second half of the rounds get huge. In the last mission I've made it to I've had about 40 of my own fighters paired with 3-4 capital ships fighting off 3 waves of something like 30-40 fighters each and then facing 3ish capital ships. You get better scores by killing enemies quickly, either within a set time limit or within quick succession to get combos, and upping a score multiplier.
It's a game worth playing, maybe even on it's own, if you're in the mood for some spacy arcade action. I might even recommend it more than the original game because it strips away some of the stuff that might have dragged down the original game a bit and the price can't be beat. Again, it's getting middling reviews I think it's just largely being overlooked. The mechanics, while simple, take a bit of getting used to in order to really dig into the meat of the game. While I beat the first game (which has been patched to be easier since then), I've really gotten better and learned how to use shifting between mech and fighter mode often and quickly to get the most out of speed, firepower, and energy management because how Infinity forces you to be more efficient to get better scores and save enough buddies to have a large enough fleet for the next round.
Also, the original game just updated in two major ways within the past week or two. First, it's now a Steamworkshop game which means mods should be coming out. I haven't played any of the sample ones yet, but it looks like someone made something like a Wipeout clone (IDOL!), an Asteroids clone, and a 2D shooter. Second, a story DLC has come out although I don't know how that is yet.
In a lot of ways this game has really become a favorite of this year. Certainly better games have come out since then, but it's better than it's getting credit for. Currently there's a sale on Steam to get the entire package and I'd bet money this is one of those games that gets deep discounts during the summer Steam sale, so it's cheap. Really, space battles! Get it.
