I've been playing this game since before it was released. It is a VERY solid SHMUP with tight controls, smart level designs and a brilliant orchestral score.
Also, EPIC BENDY LAZORS!
Definitely check it out!
This is everything I'd hoped A.R.E.S. would be. Amazing visuals, great soundtrack and rock solid gameplay.
Imagine an omni-directional, physics enabled Metal Slug and you're on the right path to describing Intrusion 2.
Pay it.
HIGHLY RECOMMEND!
This game really is pretty amazing. It went out and pioneered an interesting control scheme and play mechanic that really seems to work.
It takes a few to really get into, and there's some super tough (frustratingly tough even) stages kinda early on... but it really is FANTASTIC if you give it a chance!
