Infinite health, ammo.
The objective is simple: escape the evil research facility Helltowers with your life.
Note: There are prisoners to save in this game, but I omitted their dialog and any interaction with them in this version to quickly get it finished. This doesn't effect beating the game though.
Here are some tips for the difficult parts:
- Always shoot repeatedly and fast (especially with the Zappers).
- When you dodge, you can double tap the up key and it will always work.
- Save up HV ammo for the 2 lower levels (purple and dark areas).
- Don't waste EX ammo on Zappers (you'll likely miss and waste the few EX ammo there is).
- When shooting Zappers, wait till they get to their highest point and hit them twice.
- Use HV ammo on Zappers if you have any (you'll destroy them in 2 hits).
- If you can't beat a Zapper coming after you, walk out of the screen (if you can) and come back.
- EX ammo is useful if you're being attacked from both sides and you want to quickly dipose of one or both enemies.
If you follow these tips you should be able to beat the game in 3 or 4 tries. :)
