The Aliens behave about the same as the Ants in Abuse. They can claw and pounce at you, they can fire missiles and lasers as well. No ceiling walking yet. Different colors fire different weapons, though it may be a bit difficult to spot the different colors from colored lighting.
It is possible that the missile, laser, etc firing will be part of some other enemy instead. But for now, it will be part of these enemies. They're firing the stuff from their eye/mouth thing (also known as "skul gun").
They don't have new sounds yet. I may animate all the monsters first, and then do sounds.
I was also experimenting with some energy, stamina, air, respawn stuff for player, but eventually that felt a bit unnecessary. Now it's just Powerups, Weapons, Energy, Health and Ammo. The powerups and Shield use the energy. If you take lots of damage, you can't use the powerups for a while, or if you use the powerups long enough, you don't have shield. You can have one powerup at a time. The powerups could be: Flight, Speed, Invisibility and Regeneration.
Player's health and energy regenerate on their own very slowly. But this is more like, you have 99 health, and some 10 seconds later you have 100. This way you wouldn't accidently pickup some medikit and waste it. It would take 16 minutes 30 seconds to get back to full health from 1, so better find those medikits then.
Player can stay underwater indefinitely. Pretty sure that space battle armor suit has more than 60 seconds of air. Self damage from explosions is removed. Falling damage is removed. Player can jump some 128 units high (maybe it's a bit too much?). The speed powerup also allows double jumping.
