I got the platinum last night. HUGE CTR fan so was pleased to get it. After the first couple of attempts at Crash Cove Oxide trial I was beginning to resign myself to never getting the platinum!
The oxide trials are definitely tough on the whole, more so than the original it seems though hard to judge as I was younger and more physically/mentally nimble then! Hardest tracks for me were definitely:
- Crash Cove; you basically have to drive perfectly, there aren't many opportunities to get ahead and you can't make any mistakes no matter how small
- Blizzard Bluff; the mini shortcut at the start is quite tricky to get perfect 3 times in a row, and for some reason I struggled with getting the right angle on the ice lake to approach the river jump in order to clear the gap
- Dragon Mines; because fuck that spiral ramp
- Sewer Speedway; it took me quite a while to work out the proper way to approach the shortcut, which seems to be different to the original. Basically you need to come at it straight on (I swear you used to be able to approach it at an angle and still work), don't get greedy boosting right before you jump and hop at the very last millisecond after clearing the lip
- Deep Sea Driving; this track is garbage, too much luck involved in avoiding the numerous spinning blades, and the track behaves really strangely in certain parts, like there was a section of the consecutive jumps in the tunnel after the first spinning blade that kept slowing me down for no good reason
- Oxide Station; though only until I worked out the value of hopping sometimes vs drifting (like after getting ultra sacred fire towards the end and hopping your way through the various turns rather than drifting), plus the n tropy time on that track is ridiculous, let alone the Oxide one!
Couple of general tips (some have been mentioned already):
- to boost on a straight, hop but turn at the very last second to minimise the angle change while you're in the air
- once you get sacred fire (basically by perfect boosting on certain speed pads), make it a priority to maintain it by perfect boosting at least once every 4-5 seconds; if you can't manage the track whilst boosting during sacred fire (e.g. if turns are too tight or frequent like on Oxide station), then learn to hop your way around corners
- as much as possible, get perfect boosts; I'm not actually sure if 2 'good' boosts are better than 1 perfect, except during sacred fire when perfects do seem to be better at maintaining it
- pick a 'fast' character and learn how to handle them (I recommend Penta over Tiny/Dingodile as he's small so his model doesn't obscure as much of the track as the other chunky fast characters); you can beat oxide on various tracks with other characters, but the speed advantage is really valuable
- always take shortcuts; if you miss one on a lap (e.g. sewer speedway), you're going to lose so start again
- turn corners as tightly as possible without hitting the scenery (kinda obvious but you'll save a lot of time)
- PRACTICE AND DON'T GIVE UP TIL YOU BEAT HIM!
