infected shelter is a great roguelite brawler. the latter means you'll be beating up all sorts of bad guys (or former bad guys, now zombies or mutants), robotic creatures and even some crazed wild animals, while the former means you'll be dying and restarting from the beginning a lot. there are 4 classes to choose from , each with their strengths and weaknesses. they're all unlocked from the get-go and before every run they come up in 3 sets of randomized gear. pick one, then go nuts with whatever you can find, or use your bare hands. or your guitar, crutches, or grandpa in a wheelchair. the game doesn't take itself seriously, which was a plus for me. there are also combos to pull off for more damage. the game has permanent progression in the form of blueprints for character improvements, weapons, clothes, skills and relics, so no run is wasted. most of your money will be lost on death, but not the blueprints you find, nor the currency needed to unlock them, and they unlock for every class, no need to upgrade each separately. another thing to keep in mind is when a blueprint is unlocked, you get the item as well , just that one time, so you can be tactical, save currency for something better mid-run from the chief a couple times in each biome, instead of unlocking everything at the base. character improvements include stat upgrades and some other neat stuff I won't spoil here, while weapons come in melee and ranged varieties. they both break after some use though, and you can only carry one at a time, but whatever the enemy drops (including their heads or arms) can also be used, even barrels, car tyres, lamps, or the occasional grenade. class-specific default weapons (guitar, crutches, etc.) never break, but you can find alternatives for them during runs as well. clothes serve as armor, and while you can have 5 skills on you (they're buff, enemy debuff, offensive and defensive spells, so to speak), only 4 of them can be assigned to hotkeys and can be used over and over, but take time to recharge. relics and pendants are items with passive bonuses, both last for the entire run after you find or buy them, but pendants can be stacked, so you can have multiple of the same for a better effect. pets are also available, can be bought or found as well, as many as you want, but they also go away when you die. there are a bunch of areas to clear in a biome (or zone or whatever you wanna call it), ending in a boss fight, and this is where the best feature of the game kicks in: biome randomization turns on after beating the first boss , meaning you won't have to go through the same forest-mine-forest-boss routine every single time, you might start in a snowy forest or the city, with their respective enemy pool and boss at the end, and there are no biome-specific drops to worry about. permanent progression is one thing, but if I have to re-do the same location a million times to finally get to the second one every now and then, and possibly never see the third, it's a big turn-off for me, that's why I don't play games like this often. and that's why I was really happy to have beaten the first boss after 5 or so runs, then the game became a lot more varied. the desert is only available as the last location, so to win the game you have to go through all 4 biomes and defeat every boss in one run , which wasn't something I was aiming for, knowing how bad I am at games like this, but on my 29th run, after about a dozen hours, I somehow managed. item and enemy variety is pretty good, dozens are available of everything , and you can find survivors who'll take up residence at the base and provide much-needed provisions before runs. elite enemies can be really annoying, but blueprint drop frequency is decent, though towards the end I had runs with none, even bosses didn't drop any, which was a bit annoying, and if you want to unlock everything, you'll be playing it for a long time. I had about 2/3 of them unlocked by the time I was done, all the stat upgrades and most of the other stuff. most of the technical necessities are available , windowed mode, resolutions, volume settings, camera shake (when turned off, there's just a barely noticable one to indicate that the area is cleared of enemies and the reward crate is about to drop), camera zoom for executions, rebindable controls, but the splash screen and intro have to be skipped every single time , really annoying. multiplayer supports up to 4 players . didn't have a chance to try it, should be fun though, you can resurrect each other, so as long as somebody's alive, there's still hope. there are 2 major flaws: first of all, potions stay unidentified within the same run . you're supposed to try them, find out what they do, then ignore bad ones for the rest of the run, but here you gotta remember shape and color unless you have a specific relic to identify them. can be really annoying when you keep chugging debuffs. and secondly, there is no save & exit option , which usually ends up being a dealbreaker for me, hate it when games waste my time, but you're unlikely to have a longer run than an hour (my last one when I reached the end with a ton of luck and good drops was 70 minutes), so maybe don't start this if you only have 20 minutes to kill (though most of my runs were around that mark), and even if you have to get yourself killed because real life comes calling, you'll keep blueprints and the currency to unlock them, so not much is lost. besides addressing these, I'd only like a quick heal hotkey , as combat can get really hectic and finding and using the appropriate healing item from the inventory can be next to impossible in time. I guess it's part of the challenge, but a key to use the most powerful healing item (or more intelligently, the most powerful item considering the amount of health missing) would be great. I had a lot of fun with the game, surprisingly so, as it wasn't even on my wishlist after watching some gameplay from the early access period, but I picked it up on a whim when it was on sale and I'm really glad I did. can whole-heartedly recommend it even as a solo experience, and if you have buddies to play with, I'm sure it'll be a hoot.
