I know, I know, two suggestions within a week. However, this is a game series I've grown to love. You can try the first game, Lethal Application on the daisessen website for absolutely free
. I would suggest localizing Lethal Application if it wasn't for the fact that the game was released publicly for absolutely free
ever since a few years ago. Not to mention, I have a very shoddy translation of Lethal Application handy.
Lethal Crisis and Lethal Crisis Protosphere, however, are both games that have been mostly ignored by the masses. In fact, I actually bought and own a hard copy of Lethal Crisis, since no copy of it exists on the interwebs. Since Himeyashop and Paletweb are pretty much destroyed due to the TSA regulations, Protosphere is no longer within my grasp. You can try the demo for the game on the daisessen website, protosphere plays very much like a roguelike in a sense.
Lethal Crisis is very much an action game. You have an energy bar and everything aside from walking and jumping uses energy. There is also a flight mechanic (also known as the vernier thrusters) that uses energy. Energy is replenished whenever you stop using energy and you can equip modifications and different modules for different weapons, etc. There's objectives in game where if you complete them, you unlock more modules or increase your energy capacity or life capacity.
The game also features a burst mode system... where if you hold a button down, you'll enter "burst mode". Basically it refills your life, gives you two mirror images of yourself (think fortune summoners) that copy your moves, energy refills much faster, and your life bar depletes over time... rapidly. This mode lasts until you either die or beat whatever level you're in.
The graphics can stand to be better at times, and it is a bit low on production value... soundtracks are reused... but look into it... it's a fun little game with a pretty epic storyline. Both games are available as demos on their website... go try it...
I also know NOBODY owns the license for any of Daisessen games because the game is pretty much under radar.
