This was a good release, here is a list of stuff I noticed again:
1. Picking up a Berserk Pack switches to Doomguy's fists instead of Kyle's.
2. Hoth Trooper is still OP, he deals 10 damage a bullet, which is more than enough to decimate you, I recommend 2 damage a bullet.
3. Shield Boosters can be picked up regardless of armor cap.
4. There needs to be a Shield Booster that gives 100 shields in place of Green Armor pickups.
5. Blue Armor pickups need to be replaced with Shield Supercharge pickups.
6. Trandoshan is insta-kill to players at 200 HP and Shields or less.
7. Endoskeleton and Dark Trooper walk too slow.
8. Dark Trooper does not fly around enough or fast enough
9. DF1 units that replaced vanilla doom monsters do not set off map triggers.
10. Pakered Mortar Gun is too weak to use, recommend 3x damage buff.
11. Stouker Concussion Rifle needs to be balanced, it is the most dominate weapon in the game, it 1 shots Dark Troopers and only costs 4 cells to fire.
12. Thermal Detonators are also too weak, recommend a 2x damage boost.
13. Recommend replacing Toxin Barrels with Ion Canisters
14. Recommend decreasing damage from Storm Troopers and Officers.
15. Berserk Pack should be replaced with Weapon Supercharge pickups.
16. Megaspheres should be replaced with Revives.
17. Probe Droids and Dark Troopers do not drop ammo
18. Jeron Fusion Cutter needs a buff, recommend 2x damage.
19. Assault Cannon alt-fire needs a damage and radius buff.
20. Stormtrooper Laser Rifle ROF is slightly slower than what it should be.
21. Imperial Repeater Gun ROF is slightly slower than what it should be.
On the subject of Concussion Rifle, I would recommend that you tone down it's damage vs Gamorreans, Dark Troopers, Endoskeletons, and Trandoshans. Also, I would increase the amount of cells used per shot, say maybe 40-50? It will keep people from ROFL-Stomping the entire game once it's picked up, and allow the use of other guns.
The Assault Cannon rocket alt-fire needs to be buffed as well, this rocket should be killing anything small instantly, and bigger targets in 1-3 shots on impact. Radius could use some increase too.
