Yeah, sure, I can whip something up real quick. Keep in mind that I'm a madman who loves large endless games over the default ruleset, so Results May Vary.
Game start (Human): Get a weapon. They're the blue boxes on the minimap, and one spawns for each starting human at the start. You're basically naked without some kind of weapon as you will lose 1V1s against most monsters, so this is your TOP PRIORITY.
Once you have a weapon: STEAL EVERYTHING NOT NAILED DOWN. Other weapons can be traded to NPCs to help keep them from joining the enemy's ranks, items can be given away or (rarely) kept for yourself, and crafting materials are a special suprise that will help us later. Note that last bit, since if you find the rare and illusive 'oUtSiDe' you can pick flowers and loot graves for stacks of materials... assuming NPCs don't yoink them first.
Once you're approaching the item limit, find the Trader and/or the Cauldron. The Trader will take useless junk and give you weapons and crafting materials. She works on 'roughly' giving 1 item for every 2 you give her, and values different types of items differently. So, give her two bricks and she'll give you the Javelin. More importantly, is the crafting materials she sells. The Cauldron can be used to craft some of the best items in the game at an alarming rate, and is the key to late-game supremacy. Don't experiment blindly, read the bookshelves for crafting recipes and follow them closely.
If you're playing Portals, you can find a randomized recipe for a Sealing Stone that will cut off Monsters from accessing the mansion. If playing Keys, there will be a key in the mansion that opens a door, behind that will be monsters and another key, so on and so forth until victory. If playing Star... thing, just find five star pieces in glowing objects and put them in a pillar to win. If playing with the Lady... keep your head down and let the NPCs figure it out?
Game Start (Generic Monster): RUN. RUN FOR YOUR LIFE. You have a very short amount of time where single Humans will run from you, but once they get weapons, they'll just kill you dead. Go to either the top or bottom floor and get as far away from the staircase as possible. NPC humans wander the mansion aimlessly when not solving objectives, and as they pick random rooms and then walk to them, it is safest for Monsters to be in the most remote corners of the Mansion.
Once you're 'safe' you can start thinking about fighting back. Now, humans are deadly fucking dangerous because you don't know what they're carrying... but they do. If they think they can't beat you, they'll run and break line-of-sight, dashing to get out of the room with you. You'll need to chase them down, deplete their stamina, or abuse their AI by stepping in and out of doorways after cornering them. If they think they CAN beat you, either by having a good enough weapon, you being injured, or their being friends around, they will run straight up and murder you dead. Not even breaking LoS will stop them as they will check the last place they saw you before giving up, and they are much faster on their feet then you. Having room to retreat and hide is a must, though if you pick a fight you can't win, you're dead. You need to ambush lone individuals, preferably with backup, and don't let them pull you into a group or you will be dead FAST. Don't get attached to your AI buddies, they have the self-preservation instincts of lemmings, so play it slow and careful. Eventually, the balance will tip in your favor, and you'll win soon enough. ...If playing with exits, just run in and die, lul, you don't have time to play any smarter.
Game Start (Home Monster): Oh boy... So, plenty of monsters have a place where they NEED to be to actually transform anyone, a specific room or type of room. Problem is, most of them don't actually SPAWN there, so RUN FOR YOUR LIFE is still mandatory because if you can't TF, you can't kill, and you'll be unhappy fast. Even those that do spawn at home then face the RNG gods, because instead of running to a safe place and ganking random people you just have to kind of hope your home is out of the way and no packs of Humans just walk in and murder you. Still, it's more interesting then just walking around killing people, and some have some really neat gimmicks that make it worth looking into.
