- There are no repair stations or use-it-or-lose-it health drops like Descent. Use repair kits as soon as you're at least 25 points below max health, there's no point in hoarding them.
- Those glowing boxes with sparkles coming out of them are chests, not scenery. Maybe everyone knows this but me.
- If you enter a room through a door with a glowing purple rectangle, it's a miniboss room. Trying to open the chest will spawn the miniboss. The rewards are greater than for a normal chest, but you're locked in until you kill everything or die.
- Ramming sucks, don't bother.
