So, seeing as I recently went to replay this, discovered my own copy had been corrupted, and could only find either multipart 50 kb/s downloads or a torrent with only 1 seed, I decided to bite the bullet, and go through with it, then come back and help everyone out. I also figure giving the thread a poke will let anyone who's newer and never had the oportunity to play a chance to find the game, and other people to remember it exists.
I really wish Bias Factory had made some follow up games after this one. This is really a gem, with really interesting strategic gameplay, and great CGs in a genre that isn't particularly common and was done very well.
Also for those of you that are less interested in the gameplay (why aren't you? It's great!) I have included my full save. You can either load the save from the bottom of page three, and everything will be unlocked, and you can replay any level that you want, or you can just watch the scenes from the main menu by clicking log, selecting the scene you want, and then clicking Allplay, to play the whole scene. Because of the way they are unlocked, you can also select just parts of them to replay if you want.
If you want to actually play the game yourself, I have the following strategic advice, some of which has been mentioned previously in this thread, but I'm reiterating here to have most of it in one place:
-You can at any point in time, open your menu by right clicking, and return to camp by clicking the camp button. This gives you points for however far you had gotten just the same as if you had beaten the stage. You can use these points to heal your self and repair your armor very cheaply (you should always do this) restock your limited supplies, and upgrade your equipment.
-From this right click pause screen, you can also click on any enemy or boss part you can see and see it's attack range highlighted in red (from it's current position, it might move) and if you click search in the bottom right you can find it's weakpoint automatically, rather than by trial and error. It costs some of your time, but doesn't actually let anyone else move, so you don't risk being attacked back when you find weakpoints just running out of time. Scanning for a weakpoint like this takes 2 time units on a normal enemy, and 5 time units on a boss segment (this actually means that buying the boss weakpoints from the store is cheaper, it only costs 3 time units there, but it does use up one of the store charges that you could have used for something else, and uses time from the normal levels, which is often more important than time in the boss level.)
-Upgrading your knife increases the damage it does, and upgrading your guns increases the amount of ammo you can carry at once. Same goes for the grenades and rockets, upgrades let you carry more.
-There is an advantage to competing the level in the first run without ever returning to your camp. It gives you an extra 50% of the points you earned from the stage, which is a pretty large number if you do it all in one go. I also know for a fact that its is possible to do it in each stage as I beat the game without manually returning to camp. However, it will probably require some save scumming tactics if you do it.
-On the topic of save scumming: As far as I'm concerned the game was brilliantly designed such that you can save scum, or not, and both tactics are both valid, difficult, and doable. If you decide not to save scum, you should approach it like a rogue-lite. You will die sometimes to RNG and bad luck, but each time you do, so long as you choose restart, not load, you'll get all the points you would have earned from just retreating to camp, all your health and armor back, some of your ammo, and can restart the stage from every third floor you reached, or the boss room if you made it there. You can upgrade your equipment, restock, and get a bit further each time until you've beaten the stage. If you decide to save scum, your strategy changes a bit in that suddenly the most important thing to do on each new floor is to find the save point as quickly as possible. Once you do, you can use the time you have left to map out the level, reloading the level every time you run out of time units, until you know where all the traps and enemies are, where the exit is, and where the weakpoints on all the enemies are. Then do one last run to clear out everything you want from the level, and jump down into the next level. This all works, because the main positions of everything are loaded when the level starts. The enemies will always be in the same place, the traps, store, exit won't move if you load from a save point on that level. Each level also has a tile that can give you a grenade, a tile that can give you a rocket, and a tile that can give you 10 time units, and these will also always be in the same spot, so keep your eyes open on your random tile drops. Some aren't random. The rest however, are, which is why even after you've mapped where everything is, if things go wrong, say you jumped down into the next level, but had horrible spawn luck and activated three enemies with your first three moves and want to restart. Reloading and jumping down again will work to randomize that level again, but it will also randomize your drops again, so if the first time through you had a bunch of health and armor drop and went into that level fully healed, maybe next time around you get lower numbers on some of the tiles, and ammo from some others, and so start the next level with less health and armor, even if your starting luck is better. There's still randomness to it, and deciding when to stop and save, and when to just make do becomes a very important decision. I personally used the save scum method, and made grid maps with a pen to keep track of everything, but this is all just potential advice. It's entirely up to you how you play it. Oh, and one last thing to note if you save scum. You can use the store if you find it to pay some time to find the weakpoint of one section of the boss at a time. The thing is though, those weakpoints are decided when you start the stage, and don't change, so you can save scum to figure them out, write them down off to the side, and then reload to have the info without paying. It won't show up on your screen, but so long as you either remember or keep notes, you'll still have the info when you reach the boss.
