TIPS: Hit tab to set tactics, I usualy have mine on cowardly, don't know the difference but it seems to make your person more carfull. I.E. Blow up a barrel and he moves to dodge it.
SHOTGUNS: They have KNOCKBACK! Pinkydemons are medium speed and can keep your pace. Use the combatshotty to fire and then retreat 1 square to load a shell, then fire again, you will quickly outpace him. Shotguns are easily the best weapons in the game if you use cover properly. Single and double shotty pale in comparason because of combat shottys tactical usefullness.
Save your rocket launchers for later, those baron of hells and hellkngihts are a bitch, often taking more than 3 rockets to kill, while you get 6 fireballs in your face in the process.
TRAITS: The cateye trait is the most important trait you can have, it increases your sight range. With it at its highest level, you can outrange those pasky former human captains and thier pesky chainguns, and see HUGE threats before they supprise YOU.
SOUND: Sound is very important in this game, with all the original doom sounds imported, and with directional relevance, listen.... even stop and hit the '.' button to wait a turn, just to hear the sounds. Listen for strength of sound, direction of sound, and type. If you hear a baron of hells roar real close and to the left a bit, and your near a door... back away... FAST, and hope they don't hear you or open the door.
Clear levels, don't just skip to the next one if its right in front of you. Try to get all the nice weapons.
Always enter the red stairs to go to secret levels. Like hells arena, and the chained court, and..... the WALL (OMFG HARD)
HELLS ARENA: Never enter it unless you have a combat shotty, with usualy 3-5 pinky demons, and 5-7 lost souls, and also 1-2 coacodemons, you better be able to move while shooting, helling dodge and outrange. This is very hard considering its available often just only on the second level....
Chained court: Very simple, grab a berserker pack, OWN PEEPS, gab another to heal to 100% rinse and repeat.
The WALL: OMFG AVOID UNLESS UBER EXPERIENCED. comes at around level 7-15 this is a very deadly place. When you enter there you are outside in a hellish area, with a wall in the distance covered in blood gore limbs and pools of blood below with the screams of hell knights in the distance... multiple ones... At first theres no way for them to get to you, but with a rocket launcher that can be solved quickly... Blow open the wall about 4 times, they will rush out. Almost 100% of the time completely owning you. 2 hell knights and 1 baron of hell I saw...
Phase devices: save these and use when in a SOL situation. But it may just put you right back into one.
