Keypoints to ALL achievements (thanx darkmike!)
Spaced: eject yourself, or wait for count down
Escape Pod: Use escape pod when you acquire access card, done!
Hull BReach: Just blow yourself up in the iso ward/lab, done.
Lost in Space: Suit up@ airlock, decomp, open ext door, float out, grab the last piece of crystal among debris, then use decontamination tactic.
*put on spacesuit so no need to fix fan
Tip: purposely stay on stage 1 to save up for purchases on car 2.
But try to beat car 2 stage ASAP as car 3 earns you money so fast there's no point of saving up at car 2.
Some tips:
Buy the 1st weapon upgrade asap and save money by not purchasing armor.
If you don't get voucher before Day 10, restart.
Use your exilir if you see the voucher coming if possible
so you have as much as health for the enemy you're going to use your voucher on.
After you prioritze weapon upgrade, stock one elixir and use armor upgrades only if your health is low.
If you encounter more vouchers along the way, buy armor once
your health drop below half.
*Having elixir can help you defeat dragons if you're weapon is good enough.
Upgrades I chose to not unlock: crossbow's break armor, mage's curse and mighty curse.
You can win the game and complete all hard levels without them.
6 Sniper + 1 blue and dark mage. Is my standard deployment.
Blue for longest range and attack, lightning is so-so.
Dark mage is boosts the ice spell, which basically immobilize 1/4 screen enemies from the battelfield instantly.
6 archers for pure giant stage is useful to keep them perma stun.
Invest early stars on archers and warriors, specifically the direction which increases the unit number.
great game.
A lot of fun once you get a hang of it.
For the ogre boss on nightmare difficulty, make the wizard target the boss and feed him torch or lighted wood stick so he makes a lava field at the ogre's feet dealing continuous dmg.
