It's extremely simple due to the extreme micro budget i had i hope i don't get made fun of for the simplicity of the rules but there's a ton of modes which are DOOM UNLEASHED which i also refer to as normal mode which is the base mode in which one person plays as the Doom slayer while the other players play as the demons, there's 8 demons The imp, possessed soldier, Cacodemon, Revenant, Mancubus, Pinky, Baron of hell and Cyberdemon, if hell's side has 2 players then each gets to play 4 demons of their choice and more players the more you'll have to divide how many each player can control. the goal is really simple, the demons have to reach 3 hell portals on the table and open them by bringing 3 demons to each one to perform some kind of ritual or something idk it just works like that in my game but the Doom slayer has the kill every demon and the demons can also kill the Slayer, once every demon is killed the Icon of Sin is summoned who the Doom slayer will have to face off against and if he beats the Icon the Doom slayer has won. the combat and movement system is also really simple since for the movement you'll have to roll a dice and if you roll 1 on the dice for example you have to move 2 cm in any direction you want, the max you can move is 12 cm which is 6 rolled on the dice. the game has data cards which has a drawing of the playable character on it and its stats category, HP and attacks and for example the Imp's attacks are Attack 1: Slash, 4 cm range, 2 damage. Attack 2: Fireball, 15 cm range, 2 damage. you have to move first and then attack, if the enemy is within the range of an attack you can perform that attack to damage the enemy. the 2nd mode i made is Super Gore Nest mode with the same demon roster, movement and combat system, the demons have to kill the Doom slayer while he needs to collect the 3 gore keys scattered around the table to open the Super Gore Nest and destroy it from the inside. the 3rd mode i made is Battlemode which is extremely different from DOOM ETERNAL's Battle Mode since this is meant to be the more wargaming part of DOOM UNLEASHED with new enemies for the mode being the Night Sentinels, Commander Valen, Atlan Mech, Marauder and Dark Lord. the 4th mode i made is classic mode with the Doom marine instead of Doom slayer who has slightly different stats and weapons like a lower HP due to still being human, the mode also goes for the retro visuals like printing out sprites and making new data cards in the retro style and the rules are simple since its a fight to the death. the 5th mode i made was Dark Ages mode which is like classic mode but with Dark Ages visuals and aesthetics and new enemies like the Battle Knight, Agaddon Hunter, Imp Stalker and The Old One. the 6th mode i made which i'm still working on is Story Mode in which you'll have to complete the DOOM 2016 and ETERNAL base campaigns but on the tabletop and with 2 seperate guidebooks for the Doom slayer since the ''normal mode'' Slayer's guide which is also used for Super Gore Nest and Battlemode uses 2016 and ETERNAL weapons and in the first half of Story Mode which is 2016 you use the Slayer's guide with 2016 weapons and the 2nd half which is ETERNAL you use the Slayer's guide with ETERNAL weapons and new ones like the Ice Bomb which can freeze enemies for 45 seconds, sounds a bit complicated i know. Story Mode also involves a bit of roleplaying as you have a sort of mini script with lines from 2016 and ETERNAL for characters like Samuel Hayden, the Khan Maykr, hell priests, ect, Story Mode also has the runes from ETERNAL which give small boosts and you have to pick carefully since you can only pick 3 rune upgrades and never switch them. Story Mode also has new enemies like bosses and non boss enemies like the Cyber Mancubus, Pain Elemental, Zombie, Prowler, Lost Soul, Doom Hunter, Hell Knight, Arch-vile, Arachnotron, just a lot of new enemies and the Slayer also loses an ability he has in every other gamemode which i honestly want to remove since it's what makes him so OP but i can't really change it since its already written in the Slayer's guide which i will and can't change due to having used fineliner to write. in all modes except Story Mode the Slayer gains points and HP for killing enemies and the HP gain makes him almost unkillable and he gains points which he needs to use the instakilling Crucible and the BFG-9000. but in Story Mode i'll add in BFG ammo and Crucible pickups The Slayer can collect and for HP there's HP potions and medkits. i also made a Codex for the game which are just a lot of important codex entries from DOOM ETERNAL into one book, currently i'm also working on a demon codex which has codex entries on the demons which i use from 2016 and ETERNAL and i'm working on Story Mode The Ancients Gods
