I haven try replaying the same mission so I dont know if we could earn the credits over and over again but how do you spend your credit?
so far I bought the turret for bunker only... The best defence is offence

I usually try to buy the stuff for units I use, you won't have enough at the end of the game to buy all of the armory stuff so you have to choose.

Personally I bought all of the base stuff since I found them quite useful.

Then unit stuffs for the units I mostly use (Wraiths, Battleships, tanks etc.)

Yup, me havent buy anything yet...... Kkakakakaa.....

I wanna keep until higher unit appear.. kekeke

hmm... i think i got it wrong
the turret thing is suppose to be that zerg research thing
I bought that add 2 units in bunker i think

Yup... hahaha......

credit always not enough, and need to spend wisely, especially on hard difficulty. i regret spending on fortified bunker, should have spent on turret so can defense on Outbreak mission.

That Protoss and Zerg research thing can choose 1 out of 2
but the credit ones buy anything you like

Can the credits be earned if you redo the mission?

I have not tried but I do not think you can earn the credits again, would be a bit easy to spam like the first mission over and over in 10 minutes and buy everything from the beginning.
Kinda defeat the purpose

I played war hammer and they allow it. Nvm... tonight try and c
what if play on other modes such as casual, normal, hard, brutal

damn, is the credit really limited?I really hope to buy all of the things...anyway to earn more credit?

btw, should we save credit to upgrade than to buy mercenaries?feel like they are just wasting our limited credit...

Marines are given free
wonder why firebat are not available in multiplayer
I tried carrier rush against easy enemy and very easy enemy
still very noob

I definately wont spend any credit on mercenaries. in game still need mineral to deploy them... FTW... double payment

caltex station

For me I just bought upgrades for units that I will use. So far I haven't got the feeling that I'm lacking in credits. Not to mention I hired some mercs as well lol (again not all just the useful ones for me). And try to get all the research points cause if u max Zerg/Protoss research, extra research points will be 10000 credit each.

mercenaries?? i suggest you to try battlecruisers mercenaries... huahaha...

Sometime in the future, you'll regret not getting half the mercs. The Siege Tank mercs are SO useful.

I agree that the Siege Tanks ones are quite useful in the later games
Quite powerful.

hmm so far i spent credits on:

marines: stim pack + life
medic: build medic without reactor
marauder: concussion nades + life

that's about i think.

zerg research, erm, bunker turrets, perdition flamer turrets
protoss research, not enuf points i think lulz.

I'll keep the credits till i fail mission then only c which to buy
so far still ok... finish 7-8 campaign only

Used a lot to buy the stuff i use,like marauders,marines,medics,goliath and siege tank.

Still prefer the good old IG style.

Maybe now more money to vikings too.

Marauders concussions grenades are very good and helps a lot until the end of the game, marauders were quite a big portion of my defensive line up to the very last mission.

I also took the bunker turrets too, helps a bit.

Medic are good at beginning but I found myself not using them much at the end of the campaign, most of times I use marines/marauders in bunkers only so medic pretty useless at the end.
I am redoing the campaign in Hard now so I might change my credit allocation a bit more

I think medics are good if you prefer mobile army.

For me, i use the bunker turrets as a turret,until i need additional fire power, then, i only put marines in.

Need to use that flame turret more.

Concussion grenade is awesome to stop melee units.

Got Science Vessel too, which is the vehicle version of medic.

Plus with the regenerative armor, my army is harder to kill.

Well, thing is later in the game I hardly use marines/marauders or any infantry for attack, I use ships or vehicules.
infantry are good but to have the equivalent of attack power vehicules give you, you would need lots of them which then become a problem since they are all bunched up together.

Depends how you play anyway I guess, which is why this system is interesting

I am spending most of my credits on offensive abilities.

lol, I find myself blowing credits on things that I hardly ever use, or use once or twice on missions.

Still isn't so bad though, upgraded Siege Tanks pretty much can stop any attack dead in its track.

I buy one upgrade for each unit that I have in the Armory. The except is with the SCV which I bought everything.

Mercs are pretty cool to spend you dough on.

I confirmed that credits cant be earned twice but the research points can be recollected. Eg in a campain there is 3 points, you collected 2 and finish the game, you can reply and collect all 3 to get that remaining 1 point you left previously

i spent on merc and bunkers so far

Any achievements for not spending any credits? hahaha

Should i spend on the fast healing for medic? Found it useful i think.

Get it. Helps you alot during your early missions where you'll be using infantry mostly.

heal faster ok la
