Alright, so this is what I have to say.
- Akimbo system has got to go. No one can dual-wield in DOOM, not the Doom Slayer, not the Multi Player. You're not your ancestor, B. J. Blazkowicz, who
can dual-wield, you're not in Wolfenstein, and this isn't Trailblazer. You're the Doom Slayer. You kill stuff, and you get to the point.
- That being said, Double Double Trouble Trouble also has to go. Again, this isn't Trailblazer. XD
- If the Combat Shotgun's Explosive Shot is going to cost 2 shells to use, then remove its cooldown completely. Else, let it have its cooldown but have it cost 1 shell to use. That was the trade-off that was introduced in DOOM. It's a very subtle mechanic, but basically it expects that you're not going to wait around to let it cool down. Every second matters. Not only that, but you can't just use the Explosive Shot in every situation. There will also be situations where the Explosive Shot shouldn't be used. I'd rather it had the same mechanics as DOOM, where it had a cooldown in singleplayer and cost 1 shell to use.
Note:In multiplayer, the Explosive Shot costs 1 shell
and has no cooldown, though it doesn't have an instant load, and it doesn't deal much more damage than a point-blank buckshot payload.
- Implement the Mastery Challenges and Mastery Upgrades for all singleplayer weapons.
- Weapon Mods should be collected from Field Drones, not purchased via credits.
- Weapon Mods should not already have any of their upgrades built-in.
- The BFG ball doesn't kill everything it gets near to. So if it's far enough away and it explodes, monsters that the ball hasn't killed that aren't near enough to the ball upon its death won't die.
- In more recent gameplay for DOOM, the BFG ball itself now rips through non-boss enemies, instakilling them. Do that.
- Stretchy tracers for the bullet/pellet-type weapons need to go. They're ugly AF, and they're performance-eaters.
- Implement Praetor Suit Tokens and replace the Universal Credit System with the standard Weapon Upgrade Point System. Also remove
kebab crates.
- WE NEED RUNES.
- Get rid of the Health, Armor, and Ammo upgrades from the purchase menu and replace them with Argent Cells.
- That being said, backpacks should go. Now you'll have another place where you can spawn stuff.
- If it's at all possible, though it's understandable if you don't want to, use D4T's overhauled weapon sprites, complete with Praetor Suit gauntlets.
- Siphon Grenade works too slowly. The drain effect should occur 15 times at a rate of 7 times per second (so, every 5 tics), and it should siphon one unit of health at a time, times the number of affected monsters. It shouldn't siphon armor unless an Equipment Power rune is present and selected. Also, the Siphon Grenade is totally painless, so add the PAINLESS flag to it.
- Bring in all of the Praetor Suit's abilities. All of 'em.
- Chainsaw shouldn't kill instantly. Do a Glory Kill sequence with it.
- Many of the enemies (mostly zombies) use incorrect sounds for attacking. Change those to the correct sounds.
- Don't have enemies continuously wail when they're staggered. At the very most, they should just do their pain sound once, when staggered.
I think that's it. I'll let you know if there's anything else.
