I Think I Heard A Shot: Shoot First
I was going to post about Gigantic Army, but this is much better. Shoot First from indie developers Teknogames is the unholy child of Roguelikes and top-down shooters, and it's great. "But wait!" I hear you squeak, your voice reedy and choked with inferiority. "I thought Gauntlet was the unholy child of roguelikes and top-down shooters..." Oh, my boy. You have so much to learn.
Gauntlet's no bloody fun. You should know that by now. Go get a MAME emulator, a Gauntlet ROM and find out for yourself.
Or just take my word for it and play Shoot First, which feels great to control, is keen to be fair to you, has a sense of humour and even co-op! Ah, indie devs. You are too good to us.
One word of warning- hitting Esc returns you to the main menu, so any pausing should be done with the pause key exclusively. Now go, play! And if you like Shoot First and want to support Teknogames, any donation at all gets you a Donation Version of the game with 2 new weapons and a new Ice level. Strong!
