Another Metroid 2 Remake is a remake of Metroid II and it is being made by DoctorM64.
The challenge is: try to beat the game with only 99 Energy, 30 missiles and the lowest item % possible to complete the game is 7, which is composed by the bombs, the Speed Booster and a Super Missile Pack.
In hard mode:
*Energy Tanks adds 50 energy instead of 100.
*Missile packs gives you 2 missiles instead of 5.
*Super Missile packs gives one instead of 2.
*Enemies are more resistant.
*You can be killed in 2-3 hits or maybe in one hit.
*If you step on Lava or in the vines, the energy drains faster.
Actually, I have 4 Metroids left to kill (3 Alphas and a Gamma) and once you know their patterns it becomes a little easier.
Here are some videos of the Area 3 that may help you: they are from the 1.3 version.
In 2:00, the morph ball bug was fixed in 1.31 so this part got even harder.
The last Gamma was difficult to discover his pattern, but the luck really plays a role while playing.
Trying to speedrun this challenge is useless since you have to come back to a save station to refill the missiles, losing a lot of time.
