So this is a really old project of mine, initially was about GERA from the DS. Now is a Total Conversion of the all weapons from GERA Nintendo GameCube.
This mod captures the look and feel of Rogue Agent's weapons just about perfectly. The exaggerated animations and science-fictiony designs are a good fit for a game about blasting demons.
One minor quirk: the new barrels explode so abruptly that I had to noclip my way out of the first room of Barrels o' Fun. Also worth noting that the test map requires hardware rendering.
All in all, a very fun mod that that gives you a chance to play around with an underrated arsenal across a much wider variety of maps.
