Hello Housemarque community! Here are some of my personal tips and strategies for Dead Nation's campaign. I encourage everyone to post their own, disagree with mine or ask any question about this post or the game in general.
These tips are mostly meant for players shooting for a high score but they can also be helpful for players looking for better ways to survive. Keep in mind that I only play on Undead in single player (I'll play on Morbid for practice when I've been away from the game for too long and in coop but my tips are essentially for playing on Undead difficulty, but not exclusively...).
Most of these tips are gonna be obvious for many of you.. But I hope some of them turn out to be useful.
On Braindead, Normal and Grim difficulty I personally use my rifle for almost every situation. I invest in a shotgun for super zombies and a Shocker for kicks. On Morbid and Undead, I buy every weapon but flamethrower and SMG (I use them in single mission mode because they are already purchased but I use my cash for other weapons when playing Campaign). Upgrading your accessories should come before you invest in any secondary weapon. My accessories are almost maxed before I buy a shotgun..
-Mouth: Their scream will spawn hordes of smaller zombies. You want to kill this bastard right way. He won't be able to scream if you keep shooting him until he dies.
-Bombie: Blade Cannon takes care of them instantly.. If the option is unavailable, they can be killed with your rifle when you see them coming from a distance but be ready to Rush away once they get close. Use a flare if they get you by surprise.
-Jumpers: Use Rush ONLY when you see them jump anytime there is one of them in the area. Shotguns are very effective against them.
-Cutters: Always keep a safe distance.. Try to keep backing away when they're walking towards you, Rush only after they rushed you "a little" (work on the timing.. right before they take a first swing at you). Shotgun is risky but effective.. Rifle is safe but takes a while (great if you fight them one on one).. Launcher works best.
Weapons and Accessories:
I'll use "Greater than" symbols to illustrate which upgrading aspects I prioritize for every weapon and accessory.
-Rifle: Most important weapon.. Works well in almost any situation. Upgrade as soon as possible.
Rate of Fire > Power >>> Clip
-SMG: I don't use it... The reason being that I find it useful only for Screamers minions and having the quickest access as possible to my shotgun is too important. The SMG gets in the way more often then I have use for it. Plus, it's only very effective when fully upgraded.
-Shotgun: Great for Super Zombies (except Bombies, you don't want to shoot them up close), Sneakies (the zombies leaning against the wall and waiting until you get close to run after you), Fat zombies.
Rate of Fire > Power >> Clip >>> Max capacity
-Flamethrower: I don't use it... It's great to confuse zombies and give you some room to breathe BUT the problems with it are that zombies will wander off and you may lose track of where they are going.. They will come back to get you but you probably won't see them coming until the very last second. It can also set you on fire which of course, is never a good thing.. This is especially true when playing in coop. I use Molotovs instead of investing in the flamethrower.
-Blade Cannon: I love this one! Works best after tossing a flare or in narrow areas. It cuts any zombie in two but I try to save my ammo for Bombies and military zombies. No real need to upgrade but it obviously doesn't hurt..
Max Capacity >>> Blade size
-Launcher: I use it only for Cutters on Undead because it's too easy to harm yourself with it and thus hurt your multiplier.. But Cutters on Undead are NASTY so a Launcher is pretty much the best way to take care of them.
Blast Radius >>> Max Capacity
-Shocker: Best weapon in the game, in my opinion.. Great for any zombie but Super zombies and Sneakies. Essential for the last level..
Power >> Range >>> Clip >>>> Max capacity
-Flares: Will instantly distract any zombie but Cutters and Jumpers.
Duration >> Max capacity
-Grenades: Speaks for themselves...
MaX capacity >>> Blast Radius
-Mines: Can work as a neverending flare... It's important to note that using them on Bombies and military on Morbid or Undead is a waste. They'll use every detonation. If you're enough of a veteran and you remember the spots where smaller zombies are gonna sneak behind you, drop a mine before you move forward. You can then focus on Super Zombies or any threat ahead of you.
Explosions >> Max Capacity
-Molotovs: They can be VERY useful when used properly.. like in corridors or narrow openings. I try to drop them behind me so I don't walk through it but also because it can slow down your progress. You can boost through but you gotta remember that fire will confuse most zombie and they might wander off and attack you later when you least expect it if you lose track of them.
-Dynamite: Like Grenades... only much stronger.
Strength > Agility >>>> Endurance
I favor strength and agility because I want to seriously hurt zombies when I need to melee them and because mobility is the best defense. I don't care much about endurance because the idea is to not getting hit at all.. but of course, if you're struggling to survive you should trade strength for endurance here. Agility is always a must though.
-Collecting orbs is a risk vs reward affair. They lose value when they are dimming, so try to grab them as soon as possible.
-Pay special attention to the sounds. You'll be able to distinct which type of zombie is coming after you. Super zombie, sneakers, fatsos and rushing groups of small zombies all have their own sound.
-Take care of super zombies as soon as possible.. Especially Cutters and Mouths.
-Don't buy a weapon until you have some cash to upgrade them right away.. A weak weapon in your inventory will only cause you trouble.
-Try to be strategic.. Don't shoot everywhere at once.. You'll only make any situation harder if you do. In other words, finish what you started.
-Use your Rifle power shot for fat zombies.. Most will go down with one power shot but some require two. A normal shot will make them rush you and you want to avoid that as much as possible.
-Do NOT underestimate the power of melee. I like to melee and rush (almost simultaneously) when zombies get too close.
-Use your accessories. In most coop games I played, my partners weren't using them frequently enough.. Your inventory should be empty everytime you reach a checkpoint.
-You can kill zombies below you when you're on rooftops by throwing a grenade. Like at the very beginning of the first mission.
I'm hoping to see some of your strategies because I do not pretend that my way is the best way (not at all). I'd like to hear your thoughts so I can tweak my style and further improve my scores!
