would suggest the ghosts be trackable on a radar or something. In the original Pac-Man we would be able to see where the ghosts are and how they are moving so we can plan ahead. Seeing as this is FPS-styled, we should get some radar on their general direction (definitely don't want exact location as this would spoil gameplay) because we already have a maze to deal with.
Hmm, just thought of this, but would it break the balance of the game to include a final upgrade (like titan barrier and XZAC) for every unit? especially the ones that require the tech centre and/or rare units.
For $5000 budget, I got 5265 using Parachute, 7 bars of Fuel, 6 bars of Ramp Height, no sleigh, rest into Ramp Length. Assume that the relevant bonuses have been maxed and Ramp Angle adjusted to launch at 5-15 resistance.
Weird, I got all the safe zone achievements, got the "all safe zone" one, and yet some of them aren't lit up. But I can't seem to get them anymore because my safe zones are all green.
